These transceivers can operate with LVPECL or CML logic levels. The input signal must have at least a 200 mV peak to (single ended) signal swing. Output from the receiver section of the module is also AC coupled and is expected to drive into 50 ohm load. Different termination strategies may be required depending on the particular Serializer / Deserializer chip set used. The C-1XX-2500(C)-FDFB-SLCX series product family are designed with AC coupled data inputs and outputs to provide the following advantages: ■ Close positioning of SERDES with respect to transceiver; allows for shorter line lengths and at gigabit speeds reduces EMI. ■ Minimum number of external components. ■ Internal termination reduces the potential for unterminated stubs which would otherwise increase jitter and reduce transmission margin. Figure 1 & Figure 2 illustrates the recommended transmit and receive data line trminations for SERDES with CML and LVPECL Inputs / Outputs respectively.

Connections are made via separate voltage and ground planes. The mounting posts are at case ground and should not be connected to circuit ground. The mounting posts are at case ground and should not be connected to circuit ground. The ferrite bead should provide a real impedance of 50 to 100 ohms at 100 to 1000 MHz. Bypass capacitors should be placed as close to the 10-pin connector as possible.

A.0 2.5 Gbps Single Mode SFF LC Transceiver C-1XX-2500(C)-FDFB-SLCX Printed Circuit Board Layout Consideration A fiber-optic receiver employs a very high gain, wide bandwidth transimpedance amplifier. This amplifier detects and amplifies signals that are only tens of nA in amplitude when the receiver is operating near it’s limit. Any unwanted signal current that couples into the receiver circuitry causes a decrease in the receiver’s sensitivity and can also degrade the performance of the receiver’s signal detect (SD) circuit. To minimize the coupling of unwanted noise into the receiver, careful attention must be given to the printed circuit board. At a minimum, a double-sided printed circuit board(PCB) with a large component side ground plane beneath the transceiver must be used. In applications that include many other high speed devices, a multi-layer PCB is highly recommended. This permits the placement of power and ground on separate layers, wich allows them to be isolated from the signal lines. Multilayer construction also permits the routing of signal traces away from high level, high speed sinal lines. To minimize the possibility of coupling noise into the receiver section, high level, high speed signals such as transmitter inputs and clock lines should be routed as far away as possible from the receiver pins. Noise that couples into the receiver through the power supply pins can also degrade performance. It is recommended that a pi filter be used in both transmitter and receiver power supplies. EMI and ESC Consideration LuminentOIC transceivers offer a metalized plastic case and a special chassis grounding clip. As shown in the drawing, this clip connects the module case to chassis ground then installs flush through the panel cutout. This way, the grounding clip brushes the edge of the cutout in order to make a proper contact. The use of a grounding clip also provides increased electrostatic protection and helps reduce radiated emission from the module or the host circuit board through the chassis faceplate. The attaching posts are at case potential and may be connected to chassis ground. They should not be connected to circuit ground. Plastic optical subassemblies are used to further reduce the possibility of radiated emission by eliminating the metal from the transmitter and receiver diode housings, which extend into connector space. By providing a non-metal receptacle for the optical cable ferrule, the gigabit speed RF electrical signal is isolated from the connector area thus preventing radiated energy leakage from these surfaces to the outside of the panel.
