This transceiver is designed to transmit serial data via single mode cable. Functional Diagram Signal Monitor and Automatic Shut-Down 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. LEN TD TD Laser ISM Driver Power Control 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. Laser Coupling Unit e/o Laser o/e Single Mode Fiber Monitor RD RD SD RX Coupling Unit o/e Receiver 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 transceiver operates at 155.520 Mbit/s from a single power supply (+3.3 Volt). The differential data inputs and outputs are PECL compatible. 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 the optical power off 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. Note 1. We recommend to switch off the transmitter supply (VCC-Tx) if no transmitter input data is applied. Fiber Optics V23826-C18-C366, SM 155 MBd ATM/SDH/SONET 1x9 Trx, Ext. Temp.
