The Infineon Fibre Channel / Gigabit Ethernet multimode transceiver is a single unit comprised of a transmitter, a receiver, and an LCTM receptacle. 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 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. This transceiver operates at 1.0625 GBd / 1.25 GBd from a single power supply (+3.3 V). The full differential data inputs and outputs are PECL and LVPECL compatible.
Receiver
EPROM
The receiver component converts the optical serial data into PECL compatible electrical data (RD+ and RD-). The LOS of Signal (LOS, active low) shows whether an optical signal is present. The transmitter converts PECL compatible electrical serial data (TD+ and TD-) into optical serial data. Data lines are differentially 100 terminated. 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 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. A low signal on TxDis enables transmitter. If TxDis is high or not connected the transmitter is disabled. The information which kind of SFP module has been plugged into an SFP port can be read through the MOD-DEF interface. The information is stored in an I2C-Eprom inside the SFP Transceiver.

APPLICATION NOTES EMI-Recommendation To avoid electromagnetic radiation exceeding the required limits please take note of the following recommendations. 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. 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. 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. If a separation of signal GND and chassis GND is not possible, it is strongly recommended to provide a proper contact between signal GND and chassis GND at every location where possible. 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. 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. The cutout should be sized so that all contact springs make good contact with the face plate. For the SFP transceiver a connection of the SFP cage pins to chassis GND is recommended. If no separate chassis GND is available on the users PCB the pins should be connected to signal GND. In this case take care of the notes above. 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. The SFP transceiver can be assembled onto the host board together with all cages and host board connectors complying with the SFP multi source agreement.
