Description  
The Infineon SFP multimode transceiver is a single unit comprised of a transmitter, a  
receiver, and an LCreceptacle.  
This transceiver supports the LCconnectorization concept. It is compatible with RJ-45  
style backpanels for high end datacom and telecom applications while providing the  
advantages of fiber optic technology.  
The module is designed for low cost SAN, LAN, WAN, Fibre Channel 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 1.0625/1.25/2.125 Gbit/s from a single power supply  
(+3.3 V). The full differential data inputs and outputs are LVPECL compatible.

V23818-M305-B57  
Description  
The receiver component converts the optical serial data into LVPECL compatible  
electrical data (RD+ and RD). The Loss Of Signal (LOS) shows whether an optical  
signal is present.  
The transmitter converts LVPECL compatible electrical serial data (TD+ and TD) into  
optical serial data. Data lines are differentially 100 W 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-Recommendations  
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 W should be placed at the end of each matched  
line. An alternative termination can be provided with a 50 W resistor at each (D, Dn). In  
DC coupled systems a thevenin equivalent 50 W resistance can be achieved as follows:  
for 3.3 V: 125 W to VCC and 82 W to VEE, for 5 V: 82 W to VCC and 125 W 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/cage 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 planned, 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 of the cage 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 er 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.
