Description
The FIN324C is a 24-bit serializer / deserializer with dual strobe inputs. The device can be configured as a master or slave device through the master/slave select pin (M/S). This allows for the same device to be used as either a serializer or deserializer, minimizing component types in the system. The dual strobe inputs allow implementation of dual-display systems with a single pair of SerDes. The FIN324C can accommodate RGB, microcontroller, or SPI mode interfaces. Read and write transactions are supported when operating with a microcontroller interface for one or both displays. Unlike other SerDes solutions, no external timing reference is required for operation. The FIN324C is designed for ultra-low power operation. Reset (/RES) and standby (/STBY) signals put the device in an ultra-low power state. In standby mode, the outputs of the slave device maintain state, allowing the system to resume operation from the last-known state. The device utilizes Fairchild's proprietary ultra-low power, low-EMI Current Transfer LogicTM (CTL) technology. The serial interface disables between transactions to minimize EMI at the serial interface and to conserve power. CMOS parallel output buffers have been implemented with slew rate control to adjust for capacitive loading and to minimize EMI.

System Control Pins
(M/S) Master / Slave Selection: A given device can be configured as a master or slave device based on the state of the M/S pin. Table 1. Master/Slave M/S 0 1 Configuration Slave Mode Master Mode (/RES, /STBY) Reset and Standby Mode Functionality: Reset and standby mode functionality is determined by the state of the /RES and /STBY signals for the master device and the /RES and internal standby-detect signal for the slave device. The /RES control signal has a filter that rejects spurious pulses on /RES. Table 4. Reset and Standby Modes /RES 0 (PAR/SPI) SPI Mode Selection: The PAR/SPI signal configures STRB0(WCLK0) for SPI mode write operation. STRB1(WCLK1) always operates in parallel mode. Control signals CNTL[5:0] all pass in SPI mode. In SPI mode, the SCLK signal is used to strobe the serializer. SPI mode supports SPI writes only. Table 2.

(CKSEL) Strobe Selection Signal: The CKSEL signal exists only on the master device and determines which strobe signal is active. The active strobe signal is selected by CKSEL and PAR/SPI inputs.

(SLEW) Slew Control: The slew control operates only when in slave mode. This signal changes the edge rate of the DP[17:0], CNTL[5:0], R/W, WCLK1, and WCLK0 signals to optimize edge rate for the load being driven. Master read mode outputs have "slow" edge rates. See the AC Deserializer Specifications table for "slow" and "fast" edge rates. Table 6. Slew Rate Control /STBY (SLEW) 0 1 Slave M/S=0 "Slow" "Fast"

CMOS I/O Signals
System Control Signals
The system control signals consist of M/S, /RES, /STBY(SLEW), PAR/SPI, and CKSEL. For connectivity flexibility, these signals are over-voltage tolerant to the maximum supply voltage connected to the device. This allows these signals to be tied HIGH to either a VDDS or VDDP supply without static current consumption. These signals are all CMOS inputs and should never be allowed to float.
Parallel I/O Signals
The parallel data port signals consist of the DP[17:0], CNTL[5:0], R/W, and STRB1(0)(WCLK1(0)) signals. These signals have built-in voltage translation, allowing the signals of the master and slave to be connected to different VDDP supply voltages.
Serial I/O Signals
CTL I/O Technology
The serial I/O is implemented using Fairchild's proprietary differential CTL I/O technology. During data transfers, the serial I/O are powered up to a normal operating mode around .5V. Upon completion of a data transfer, the serial I/O goes to a lower power mode around VDDS.
Serial I/O Orientation Logic
The serial I/O signal traces should not cross between the master and the slave. The pin locations have been designed to eliminate the need to cross traces. See Table 7, Figure 4 and Figure 5.

SerDesTM FIN324C -- 24-Bit Ultra-Low Power Serializer / Deserializer Supporting Single and Dual Displays
Master/Slave READ Transactions
Read transactions have two phases: The Read-Control Phase, where CNTL[5:0], R/W, CKSEL are transmitted to the deserializer; and the Read-Data Phase, where the DP[17:0] signals of the slave are read and transmitted back to the master device. The slave device generates its own strobe signal for latching in the data. Slave data must be valid prior to the WCLKn signal going HIGH. Master Serializer Operation (Read Control Phase) When the R/W signal is asserted HIGH and the STROBE signal transitions LOW, the Read-Control Phase of the read cycle is initiated. The R/W signal must not transition until the READ cycle completes. For a READ transaction, only eight control signals are captured. The 18 DP bits are ignored during the READ operation. The following sequence must occur for data to be serialized properly: 1. CPU selects input strobe source (CKSEL=0 or 1). 2. CPU sends signals (R/W=1, CKSEL, CNTL[5:0]). 3. CPU sends LOW STROBE signal. Slave Deserializer Operation (Read-Control Phase) 1. Captures data from serial transfer. 2. Internally decodes that this is a READ transaction. 3. Outputs control signals and prepares DP pins to accept data. 4. Outputs falling edge of WCLK pulse. Slave Serializer Read Operation (Read-Data Phase) The slave serializer is enabled on the tail end of the Read-Control Phase of operation. The operation of the serializer is identical to the master serialization except that the strobe signal is generated internally and only the data bits DP[17:0] are captured. 1. Display device outputs data onto DP bus on falling edge of WCLK. 2. Captures parallel data on generated rising edge of WCLK signal. 3. Serializes data stream. Master Deserializer Read Operation (Read-Data Phase): 1. Receives valid serial stream. 2. Outputs data DP[17:0]. 3. CPU asserts rising edge of strobe signal to capture data.
SPI WRITE transaction
SPI mode is activated by asserting the PAR/SPI signal low on both the master and slave device. A SPI write is only performed when CKSEL=0. During a SPI transaction, SCLK must be connected to CNTL[5] and is the strobe source for serialization. SDAT is on CNTL[4] and all of the remaining control signals and STRB0 are serialized. STRB0 should be connected to the SPI mode chip select. On the rising edge of SCLK, all eight control signals (CNTL[5:0], R/W, CKSEL) are captured and serialized. The data signals are not sent. The deserializer captures the serial stream and outputs it to the parallel port. As shown in Table 2, SDAT and SCLK are output on multiple pins. The DP[7] and DP[6] connections can be used for displays with dual-mode operation and the data pins are multiplexed with the SPI signals. CNTL[5] and CNTL[4] signals can be used when the signals are not multiplexed.

Additional Application Information
Flex Cabling: The serial I/O information is transmitted at a high serial rate. Care must be taken implementing this serial I/O flex cable. The following best practices should be used when developing the flex cabling or Flex PCB. Keep all four differential Serial Wires the same length. Do not allow noisy signals over or near differential serial wires. Example: No CMOS traces over differential serial wires. Use only one ground plane or wire over the differential serial wires. Do not run ground over top and bottom. Design goal of 100-ohms differential characteristic impedance. Do not place test points on differential serial wires. Use differential serial wires a minimum of 2cm away from the antenna. Visit Fairchild's website at http://www.fairchildsemi.com/products/interface/userdes.html, contact your sales rep, or contact Fairchild directly at interface@fairchildsemi.com for applications notes or flex guidelines.

Notes: 4. Active edge of strobe is the rising edge for a write transaction and the falling edge for a read transaction. 5. Characterized, but not production tested. 6. Indirectly tested through serial clock frequency and serial data bit tests. 7. Pulse width low WCLKn measurements are measured at 30% of VDDP. Measurements apply when SLEW=0 or SLEW=1. 8. Minimum times occur with maximum oscillator frequency. Maximum times occur with minimum oscillator frequency. 9. Write latency is the sum of the delay through the master serializer and slave deserializer, plus the flight time across the flex cable and I/O propagation delays. 10. Assumes propagation delay across the flex cable and through the I/Os of 20ns. 11. Total read latency tPD-RD is the sum of the Read-Control Phase latency (tPD-RDC) and the Read-Data Phase latency (tPD-RDD). tPD-RD=tPD-RDC+ tPD-RDD. 12. Read-Control latency is the sum of the delay through the master serializer and slave deserializer, plus flex cable flight times and I/O propagation delays. 13. Read Data latency is the sum of the delay through the slave serializer and master deserializer, plus flex cable flight times and I/O propagation delays. 14. SPI-Write latency is the sum of the delay through the master serializer and slave deserializer, plus the flight time across the flex cable and I/O propagation delays. 15. Timing allows the device to completely reset prior to powering down. 16. Internal reset filter allows assertion prior to completion of read or write date transfer. 17. Timing ensures that last write transaction is complete prior to going into standby. 18. VDDA/S must power up together. VDDP may power-up relative to VDDA/S in any order without static power being consumed. Guaranteed by characterization. 19. /RES signal should be held low for minimum time specified after supplies go HIGH. It is recommended that /RES be held low during the power supply ramp. 20. STRBn must be held off until internal oscillator has stabilized.
