DESCRIPTION The SP509 is a monolithic device that supports eight (8) popular serial interface standards for Wide Area Network (WAN) connectivity. The SP509 is fabricated using a low power BiCMOS process technology, and incorporates a Sipex regulated charge pump allowing +5V only operation. Sipex's patented charge pump provides a regulated output of +5.8V, which will provide enough voltage for compliant operation in all modes. Eight (8) drivers and eight (8) receivers can be configured via software for any of the above interface modes at any time. The SP509 requires no additional external components for compliant operation for all of the eight (8) modes of operation other than four capacitors used for the internal charge pump. All necessary termination is integrated within the SP509 and is switchable when V.35 drivers and V.35 receivers, or when V.11 receivers are used. The SP509 provides the controls and transceiver availability for operating as either a DTE or DCE. Additional features with the SP509 include internal loopback that can be initiated in any of the operating modes by use of the LOOPBACK pin. While in loopback mode, receiver outputs are internally connected to driver inputs creating an internal signal path bypassing the serial communications controller for diagnostic testing. The SP509 also includes a latch enable pin with the driver and receiver address decoder. The internal V.11 or V.35 receiver termination can be switched off using a control pin (TERM_OFF) for monitoring applications. All eight (8) drivers and receivers in the SP509 include separate enable pins for added convenience. The SP509 is ideal for WAN serial ports in networking equipment such as routers, concentrators, network muxes, DSU/CSU's, networking test equipment, and other access devices.

ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation of the device at these ratings or any other above those indicated in the operation sections of the specifications below is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability.

STORAGE CONSIDERATIONS
Due to the relatively large package size of the 100-pin quad flatpack, storage in a low humidity environment is preferred. Large high density plastic packages are moisture sensitive and should be stored in Dry Vapor Barrier Bags. Prior to usage, the parts should remain bagged and stored below 40C and 60%RH. If the parts are removed from the bag, they should be used within 48 hours or stored in an environment at or below 20%RH. If the above conditions cannot be followed, the parts should be baked for four hours at 125C in order to remove moisture prior to soldering. Sipex ships the 100-pin LQFP in Dry Vapor Barrier Bags with a humidity indicator card and desiccant pack. The humidity indicator should be below 30%RH.

The SP509 contains highly integrated serial transceivers that offer programmability between interface modes through software control. The SP509 offers the hardware interface modes for RS-232 (V.28), RS-449/V.36 (V.11 and V.10), EIA-530 (V.11 and V.10), EIA-530A (V.11 and V.10), V.35 (V.35 and V.28) and X.21(V.11). The interface mode selection is done via three control pins, which can be latched via microprocessor control. The SP509 has eight drivers, eight receivers, and Sipex's patented on-board charge pump (5,306,954) that is ideally suited for wide area network connectivity and other multi-protocol applications. Other features include digital and line loopback modes, individual enable/disable control lines for each driver and receiver, fail-safe when inputs are either open or shorted, individual termination resistor ground paths, separate driver and receiver ground outputs, enhanced ESD protection on driver outputs and receiver inputs. THEORY OF OPERATION The SP509 device is made up of 1) the drivers, 2) the receivers, 3) a charge pump, 4) DTE/DCE switching algorithm, and 5) control logic. Drivers The SP509 has eight enhanced independent drivers. Control for the mode selection is done via a threebit control word into D0, D1, and D2. The drivers are prearranged such that for each mode of operation, the relative position and functionality of the drivers are set up to accommodate the selected interface mode. As the mode of the drivers is changed, the electrical characteristics will change to support the required signal levels. The mode of each driver in the different interface modes that can be selected is shown in Table 1.
FEATURES There are four basic types of driver circuits - ITU-T-V.28 (RS-232), ITU-T-V.10 (RS-423), ITU-T-V.11 (RS-422), and CCITT-V.35. The V.28 (RS-232) drivers output single-ended signals with a minimum of +5V (with 3k & 2500pF loading), and can operate over 120kbps. Since the SP509 uses a charge pump to generate the RS-232 output rails, the driver outputs will never exceed +10V. The V.28 driver architecture is similar to Sipex's standard line of RS-232 transceivers. The RS-423 (V.10) drivers are also single-ended signals which produce open circuit VOL and VOH measurements of +4.0V to +6.0V. When terminated with a 450 load to ground, the driver output will not deviate more than 10% of the open circuit value. This is in compliance of the ITU V.10 specification. The V.10 (RS-423) drivers are used in RS-449/V.36, EIA-530, and EIA-530A modes as Category II signals from each of their corresponding specifications. The V.10 drivers are guaranteed to transmit over 120kbps, but can operate at over 1Mbps if necessary. The third type of drivers are V.11 (RS-422) differential drivers. Due to the nature of differential signaling, the drivers are more immune to noise as opposed to single-ended transmission methods. The advantage is evident over high speeds and long transmission lines. The strength of the driver outputs can produce differential signals that can maintain +2V differential output levels with a load of 100. The signal levels and drive capability of these drivers allow the drivers to also support RS-485 requirements of +1.5V differential output levels with a 54 load. The strength allows the SP509 differential driver to drive over long cable lengths with minimal signal degradation. The V.11 drivers are used in RS-449, EIA-530, EIA-530A and V.36 modes as Category I signals which are used for clock and data. Sipex's new driver design over its predecessors allow the SP509 to operate over 40Mbps for differential transmission.

The fourth type of drivers are V.35 differential drivers. There are only three available on the SP509 for data and clock (TxD, TxCE, and TxC in DCE mode). These drivers are current sources that drive loop current through a differential pair resulting in a 550mV differential voltage at the receiver. These drivers also incorporate fixed termination networks for each driver in order to set the VOH and VOL depending on load conditions. This termination network is basically a "Y" configuration consisting of two 51 resistors connected in series and a 124 resistor connected between the two 50 resistors and a V35TGND output. Each of the three drivers and its associated termination will have its own V35TGND output for grounding convenience. Filtering can be done on these pins to reduce common mode noise transmitted over the transmission line by connecting a capacitor to ground. The drivers also have separate enable pins which simplifies half-duplex configurations for some applications, especially programmable DTE/DCE. The enable pins will either enable or disable the output of the drivers according to the appropriate active logic illustrated on Figure 47. The enable pins have internal pull-up and pulldown devices, depending on the active polarity of the receiver, that enable the driver upon poweron if the enable lines are left floating. During disabled conditions, the driver outputs will be at a high impedance 3-state. The driver inputs are both TTL or CMOS compatible. All driver inputs have an internal pull-up resistor so that the output will be at a defined state at logic LOW ("0"). Unused driver inputs can be left floating. The internal pull-up resistor value is approximately 500k. Receivers The SP509 has eight enhanced independent receivers. Control for the mode selection is done via a three-bit control word that is the same as the driver control word. Therefore, the modes for the drivers and receivers are identical in the application. Like the drivers, the receivers are prearranged for the specific requirements of the synchronous serial interface. As the operating mode of the receivers is changed, the electrical characteristics will change to support the required serial interface

protocols of the receivers. Table 1 shows the mode of each receiver in the different interface modes that can be selected. There are two basic types of receiver circuits--ITU-T-V .28 (RS-232) and ITU-T-V.11, (RS-422). The RS-232 (V.28) receiver is single-ended and accepts RS-232 signals from the RS-232 driver. The RS-232 receiver has an operating input voltage range of +15V and can receive signals downs to +3V. The input sensitivity complies with RS-232 and V .28 at +3V. The input impedance is 3k to 7k in accordance to RS232 and V .28. The receiver output produces a TTL/CMOS signal with a +2.4V minimum for a logic "1" and a +0.4V maximum for a logic "0". The RS-232 (V.28) protocol uses these receivers for all data, clock and control signals. They are also used in V.35 mode for control line signals: CTS, DSR, LL, and RL. The RS-232 receivers can operate over 120kbps. The second type of receiver is a differential type that can be configured internally to support ITU-T-V.10 and CCITT-V.35 depending on its input conditions. This receiver has a typical input impedance of 10k and a differential threshold of less than +200mV, which complies with the ITU-T-V.11 (RS-422) specifications. V.11 receivers are used in RS-449/V.36, EIA-530, EIA-530A and X.21 as Category I signals for receiving clock, data, and some control line signals not covered by Category II V.10 circuits. The differential V.11 transceiver has improved architecture that allows over 40Mbps transmission rates. Receivers dedicated for data and clock (RxD, RxC, TxC) incorporate internal termination for V.11. The termination resistor is typically 120 connected between the A and B inputs. The termination is essential for minimizing crosstalk and signal reflection over the transmission line . The minimum value is guaranteed to exceed 100, thus complying with the V.11 and RS-422 specifications. This resistor is invoked when the receiver is operating as a V.11 receiver, in modes EIA-530, EIA-530A, RS-449/V.36, and X.21.

The same receivers also incorporate a termination network internally for V.35 applications. For V.35, the receiver input termination is a "Y" termination consisting of two 51 resistors connected in series and a 124 resistor connected between the two 50 resistors and V35RGND output. The V35RGND is usually grounded. The receiver itself is identical to the V.11 receiver. The differential receivers can be configured to be ITU-T-V.10 single-ended receivers by internally connecting the non-inverting input to ground. This is internally done by default from the decoder. The non-inverting input is rerouted to V10GND and can be grounded separately. The ITU-T-V.10 receivers can operate over 1Mbps and are used in RS-449/V.36, E1A-530, E1A-530A and X.21 modes as Category II signals as indicated by their corresponding specifications. All receivers include an enable/disable line for disabling the receiver output allowing convenient half-duplex configurations. The enable pins will either enable or disable the output of the receivers according to the appropriate active logic illustrated on Figure 47. The receiver's enable lines include an internal pull-up or pull-down device, depending on the active polarity of the receiver, that enables the receiver upon power up if the enable lines are left floating. During disabled conditions, the receiver outputs will be at a high impedance state. If the receiver is disabled any associated termination is also disconnected from the inputs. All receivers include a fail-safe feature that outputs a logic high when the receiver inputs are open, terminated but open, or shorted together. For single-ended V.28 and V.10 receivers, there are internal 5k pull-down resistors on the inputs which produces a logic high ("1") at the receiver outputs. The differential receivers have a proprietary circuit that detect open or shorted inputs and if so, will produce a logic HIGH ("1") at the receiver output.
CHARGE PUMP The charge pump is a Sipex-patented design (5,306,954) and uses a unique approach compared to older less-efficient designs. The charge pump still requires four external capacitors, but uses four-phase voltage shifting technique to attain symmetrical power supplies. The charge pump VDD and VSS outputs are regulated to +5.8V and -5.8V, respectively. There is a free-running oscillator that controls the four phases of the voltage shifting. A description of each phase follows. Phase 1 __VSS charge storage ----During this phase of the clock cycle, the positive side of capacitors C1 and C2 are initially charged to VCC. C+ is then switched to ground and the charge in C1- is transferred to C2-. Since C2+ is connected to VCC, the voltage potential across capacitor C2 is now 2XVCC. Phase 2 --VSS transfer --Phase two of the clock connects the negative terminal of C2 to the VSS storage capacitor and the positive terminal of C2 to ground, and transfers the negative generated voltage to C3. This generated voltage is regulated to -5.8V. Simultaneously, the positive side of the capacitor C1 is switched to VCC and the negative side is connected to ground. Phase 3 --VDD charge storage --The third phase of the clock is identical to the first phase--the charge transferred in C1 produces -VCC in the negative terminal of C1 which is applied to the negative side of the capacitor C2 . Since C2+ is at VCC, the voltage potential across C2 is 2XVCC. Phase 4 --VDD transfer --The fourth phase of the clock connects the negative terminal of C2 to ground, and transfers the generated 5.8V across C2 to C4, the VDD storage capacitor. This voltage is regulated to +5.8V. At the regulated voltage, the internal oscillator is disabled and simultaneously with this, the positive side of capacitor C1 is switched to VCC and the negative side is connected to ground, and the cycle begins again. The charge pump cycle will continue as long as the operational conditions for the internal oscillator are present.

Since both V+ and V- are separately generated from VCC; in a no-load condition V+ and V- will be symmetrical. Older charge pump approaches that generate V- from V+ will show a decrease in the magnitude of V- compared to V+ due to the inherent inefficiencies in the design. The clock rate for the charge pump typically operates at 250kHz. The external capacitors can be as low as 1F with a 16V breakdown voltage rating. TERM_OFF FUNCTION The SP509 contains a TERM_OFF pin that disables all three receiver input termination networks regardless of mode. This allows the device to be used in monitor mode applications typically found in networking test equipment. The TERM_OFF pin internally contains a pull-down device with an impedance of over 500k, which will default in a "ON" condition during power-up if V.35 receivers are used. The individual receiver enable line and the SHUTDOWN mode from the decoder will disable the termination regardless of TERM_OFF. LOOPBACK FUNCTION The SP509 contains a LOOPBACK pin that invokes a loopback path. This loopback path is illustrated in Figure 48. LOOPBACK has an internal pull-up resistor that defaults to normal mode during power up or if the pin is left floating. During loopback, the driver output and receiver input characteristics will still adhere to its appropriate specifications. DECODER AND D_LATCH FUNCTION The SP509 contains a D_LATCH pin that latches the data into the D0, D1, and D2 decoder inputs. If tied to a logic LOW ("0"), the latch is transparent, allowing the data at the decoder inputs to propagate through and program the SP509 accordingly. If tied to a logic HIGH("1"), the latch locks out the data and prevents the mode from changing until this pin is brought to a logic LOW.
There are internal pull-up devices on D0, D1, and D2, which allow the device to be in SHUTDOWN mode ("111") upon power up. However , if the device is powered -up with the D_LATCH at a logic HIGH, the decoder state of the SP509 will be undefined. ESD TOLERANCE The SP509 device incorporates ruggedized ESD cells on all driver output and receiver input pins. The ESD structure is improved over our previous family for more rugged applications and environments sensitive to electrostatic discharges and associated transients. CTR1/CTR2 EUROPEAN COMPLIANCY As with all of Sipex's previous multi-protocol serial transceiver IC's the drivers and receivers have been designed to meet all the requirements to NET1/NET2 and TBR2 in order to meet CTR1/CTR2 compliancy. The SP509 is also tested in-house at Sipex and adheres to all the NET1/2 physical layer testing and the ITU Series V specifications before shipment. Please note that although the SP509 , as with its predecessors, adhere to CTR1/CTR2 compliancy testing, any complex or unusual configuration should be double-checked to ensure CTR1/CTR2 compliance. Consult the factory for details.
