The receiver component converts the optical serial data into PECL compatible electrical data (RD+ and RD-). The Signal Detect (SD, active high) shows whether an optical signal is present.

Data lines are differentially 100 terminated. The Infineon Gigabit Ethernet multimode transceiver is a single unit comprised of a transmitter, a receiver, and an LCTM receptacle. This design frees the customer from many alignment and PC board layout concerns. 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. This transceiver supports the LCTM connectorization concept. It is compatible with RJ-45 style backpanels for high end Data Com and Telecom applications while providing the advantages of fiber optic technology. 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. The module is designed for low cost SAN, LAN, WAN, Fibre Channel and Gigabit Ethernet applications. It can be used as the network end device interface in mainframes, workstations, servers, and storage devices, and in a broad range of network devices such as bridges, routers, hubs, and local and wide area switches. Single fault condition is ensured by means of an integrated automatic shutdown circuit that disables the laser when it detects laser fault to guarantee the laser Eye Safety. The transceiver contains a supervisory circuit to control 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 140 milliseconds after the voltage has risen above the reset threshold. During this time the laser is inactive. This transceiver operates at 1 and 1.25 Gbit/s from a single power supply (+3.3 V). The full differential data inputs and outputs are PECL and LVPECL compatible. A low signal on TxDis enables transmitter. If TxDis is high the transmitter is disabled.

This concept is designed to avoid hotspots. Hotspots are places of highest radiation which could be generated if only a few connections between signal and chassis GND exist. Compensation currents would concentrate at these connections, causing radiation. RS pin The RS Rate Select: is not connected. LF pin The LF pin (Laser Fault) is a TTL output of the Laser Driver Supervisor Circuit. A Logic "1" level can be measured in case of a laser fault. It will not show a fault if the laser is being disabled using the TxDis input, since this is not a fault condition. By use of Gigabit switching components in a design, the return path of the RF current must also be considered. Thus a split GND plane of Tx and Rx portion may result in severe EMI problems. EMI-Recommendation To avoid electromagnetic radiation exceeding the required limits please take note of the following recommendations. A recommendation is to connect the housing leads to signal GND. However, in certain applications it may improve EMI performance by connecting them to chassis GND. When Gigabit switching components are found on a PCB (multiplexers, clock recoveries etc.) any opening of the chassis may produce radiation also at chassis slots other than that of the device itself. Thus every mechanical opening or aperture should be as small as possible. The cutout should be sized so that all contact springs make good contact with the face plate. Please consider that the PCB may behave like a waveguide. With an r of 4, the wavelength of the harmonics inside the PCB will be half of that in free space. In this scenario even the smallest PCBs may have unexpected resonances. On the board itself every data connection should be an impedance matched line (e.g. strip line, coplanar strip line). Data, Datanot should be routed symmetrically, vias should be avoided. A terminating resistor of 100 should be placed at the end of each matched line. An alternative termination can be provided with a 50 resistor at each (D, Dn). In DC coupled systems a thevenin equivalent 50 resistance can be achieved as follows: For 3.3 V: 125 to VCC and 82 to VEE, for 5 V: 82 to VCC and 125 to VEE at Data and Datanot. Please consider whether there is an internal termination inside an IC or a transceiver. Transceiver Pitch Dimensions in (mm) inches (13.97) *) .550 In certain cases signal GND is the most harmful source of radiation. Connecting chassis GND and signal GND at the plate/ bezel/ chassis rear e.g. by means of a fiber optic transceiver may result in a large amount of radiation. Even a capacitive coupling between signal GND and chassis may be harmful if it is too close to an opening or an aperture. Fiber Optics *) min. pitch between SFF transceiver according to MSA.
