Maximum reach over fiber type SM-G.652 as defined by ITU-T G.957 and Telcordia GR-253-CORE standards. Longer reach possible depending upon link implementation.
ATM was developed to facilitate solutions in multimedia applications and real time transmission. The data rate is scalable, and the ATM protocol is the basis of the broadband public networks being standardized in the International Telecommunications Union (ITU), the former International Telegraph and Telephone Consultative Committee (CCITT). ATM can also be used in local private applications. The Infineon single mode ATM transceiver is a single unit comprised of a transmitter, a receiver, and an SC receptacle. This design frees the customer from many alignment and PC board layout concerns. The module is designed for low cost WAN applications. It can be used as the network end device interface in workstations, servers, and storage devices, and in a broad range of network devices such as bridges, routers, and intelligent hubs, as well as wide area ATM switches. This transceiver operates at 155.520 Mbit/s from a single power supply (5 V or 3.3 V). The differential data inputs and outputs are DC-coupled and PECL compatible.

Functional Diagram
The receiver component converts the optical serial data into PECL compatible electrical data (RD+ and RD-). The Signal Detect (SD, active high) shows whether optical data is present 1). The transmitter converts electrical PECL compatible serial data (TD+ and TD-) into optical serial data. The transmitter contains a laser driver circuit that drives the modulation and bias current of the laser diode. The currents are controlled by a power control circuit to guarantee constant output power of the laser over temperature and aging. The power control uses the output of the monitor PIN diode (mechanically built into the laser coupling unit) as a controlling signal, to prevent the laser power from exceeding the operating limits. Single fault condition is ensured by means of an integrated automatic shutdown circuit that disables the laser when it detects transmitter failures or when VCC is too high. A reset is only possible by turning the power off, and then on again.

We recommend to switch off the transmitter supply (VCCTx) if no transmitter input data is applied.

Minimum average optical power at which the BER is less than 1x10-10 or lower. Measured with a 223-1 NRZ PRBS as recommended by ANSI T1E1.2, SONET OC-3 and ITU-T G.957. BOL value -31 dBm max. An increase in optical power of data signal above the specified level will cause the Signal Detect to switch from a low state to a high state. A decrease in optical power of data signal below the specified level will cause the Signal Detect to switch from a high state to a low state. DC/DC, PECL for Signal Detect, PECL compatible. Load is 50 into VCC-2 V for data, 510 to VEE for Signal Detect. Measured under DC conditions. For dynamic measurements a tolerance of 50 mV should be added. VCC = 5 V/3.3 V. TAMB = 25C.

To meet laser safety requirements the transceiver shall be operated within the Absolute Maximum Ratings. Attention: All adjustments have been made at the factory prior to shipment of the devices. No maintenance or alteration to the device is required. Tampering with or modifying the performance of the device will result in voided product warranty. Note: Failure to adhere to the above restrictions could result in a modification that is considered an act of "manufacturing", and will require, under law, recertification of the modified product with the U.S. Food and Drug Administration (ref. 21 CFR 1040.10 (i)).

Application Notes Application Notes ATM transceivers and matching circuits are high frequency components and shall be terminated as recommended in the application notes for proper EMI performance. Electromagnetic emission may be caused by these components. To prevent emissions it is recommended that cutouts for the fiber connectors be designed as small as possible. It is recommended that the Tx plug and the Rx plug be separated with a bar that divides the duplex SC opening. Single Mode 155 Mbit/s ATM 1x9 Transceiver, DC/DC PECL Version

Application Notes This application note assumes Fiber Optic transceivers using 5 V/3.3 V power supply and SerDes Chips using either 3.3 V or 5 V power supply. It also assumes no self biasing at the receiver data inputs (RD+/RD-) of the SerDes chip (Refer to the manufacturer data sheet for other applications). Value of R1...R4 may vary as long as proper 50 termination to VEE or 100 differential is provided. The power supply filtering is required for good EMI performance. Use short tracks from the inductor L1/L2 to the module VCCRx/VCCTx. Further application notes for electrical interfacing are available upon request. Ask for Appnote 82. We strongly recommend a VEE plane under the module for getting good EMI performance. The transceiver contains an automatic shutdown circuit. Reset is only possible if the power is turned off, and then on again. (VCCTx switched below VTH).
