Support Stud Pin Not connected 2 2000-03-01 V23826-C18-T64 V23826-C18-T364 Description Description The Infineon single mode ATM transceiver complies with the ATM Forum's Network Compatible ATM for Local Network Applications document and ANSI's Broadband ISDN - Customer Installation Interfaces, Physical Media Dependent Specification, T1.646-1995, Bellcore-SONET OC-3/LR-1 and ITU-T G.957 STM-1/L.1.1. 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 long haul transceiver is a single unit comprised of a transmitter, a receiver, and an ST 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, intelligent hubs, and 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 PECL compatible. Functional Description This transceiver is designed to transmit serial data via single mode cable. Signal Monitor and Automatic Shut-Down LEN TD TD Laser Coupling Unit Laser ISM Driver e/o Laser Power Control o/e Single Mode Fiber Monitor RD RD SD Figure 2 Data Sheet RX Coupling Unit o/e Receiver Functional Diagram 3 2000-03-01 V23826-C18-T64 V23826-C18-T364 Description The transmitter converts electrical PECL compatible serial data (TD and TDnot) into optical serial data. It 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. This transceiver contains an Input Signal Monitor (ISM), that switches the optical power off if a continuously low level is applied at Data Input. The receiver component converts the optical serial data into PECL compatible electrical data (RD and RDnot). The Signal Detect (SD, active high) shows whether optical data is present 1). This module is a Class 1 laser product, due to an integrated automatic shutdown circuit that disables the laser when it detects transmitter failures. Single fault condition is ensured by means of an integrated automatic shutdown circuit that disables the laser when it detects transmitter failures. A reset is only possible by turning the power off, and then on again. The transceiver contains a supervisory circuit to monitor the power supply. This circuit makes an internal reset signal whenever the supply voltage drops below the reset threshold. It keeps the reset signal active for at least 15 milliseconds after the voltage has risen above the reset threshold. During this time the laser is inactive.

Measured with a 223 - 1 NRZ PRBS as recommended by ANSI T1E1.2, SONET OC-3, and ITU-T G.957. 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 for data, DC/DC PECL for Signal Detect, PECL compatible. Load is 50 Ω into VCC – 2 V for data, 500 Ω to VEE for Signal Detect. Measured under DC conditions. For dynamic measurements a tolerance of 50 mV should be added. VCC = 3.3 V / 5 V. TAMB = 25°C. PECL compatible. A high level on this output shows that an optical signal is applied to the optical input.

It complies with IEC 60825-1 and FDA 21 CFR 1040.10 and 1040.11. 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. Do not view into the open optical port for more than 60 seconds.

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). 3.3 V-Transceivers can be directly connected to SerDes-Chips using standard PECL Termination network. Value of R1...R4 may vary as long as proper 50 Ω termination to VEE or 100 Ω 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). Application Board available on request.
