Support Stud Pin Not connected 2 2001-08-01 V23826-H18-C63 V23826-H18-C363 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 / IR-1 and OC-12 / IR-1, ITU-T G.957 STM-1 / S.1.1 and STM-4 / S.4.1. 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 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 622.080 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 *DC/DC Version only Functional Diagram 3 2001-08-01 V23826-H18-C63 V23826-H18-C363 Description 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 present1). The transmitter converts electrical PECL compatible serial data (TD and TDnot) into optical serial data. This version contains an Input Signal Monitor (ISM), that switches off the optical power if a continuously low level is applied at Data Input. 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. A reset is only possible by turning the power off, and then on again. The transceiver contains a supervisory circuit to control the power supply. This circuit generates 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.

With a field strength of 3 V/m rms, noise frequency ranges from 10 MHz to 2 GHz. No effect on transceiver performance between the specification limits. Noise frequency range: 30 MHz to 6 GHz; Margins depend on PCB layout and chassis design. We recommend to switch off the transmitter supply (VCC - Tx) if no transmitter input data is applied.

An increase in optical power above the specified level will cause the SIGNAL DETECT output to switch from a Low state to a High state. A decrease in optical power below the specified level will cause the SIGNAL DETECT to change from a High state to a Low state. DC/DC for data, DC/DC PECL for Signal Detect. Load is 50 Ω into VCC – 2 V for data, 510 Ω (5 V) or 270 Ω (3.3 V) to VEE for Signal Detect. Measured under DC conditions. For dynamic measurements a tolerance of 50 mV should be added.

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. 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)).

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.

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.
