- 7 - p/n: c-13-155(c)-fdfb-slc8a-g5 155 mbps single mode sff lc transceive r ds-5477 rev 0.0 2009-04-30 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 am plitude when the receiver is operating near it?s limit. any unwanted signal current that couples into the receiver ci rcuitry causes a decrease in the receiver?s sensitivity and can also degrade the performance of the receiver?s signal de tect (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(pc b) with a large component side ground plane beneath the transceiver must be used. in applic ations that include many other high spee d 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 t he routing of signal traces away from high level, high speed sinal lines. to minimize the po ssibility of coupling noise into the rece iver 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 po wer supply pins can also degrade performance. it is recommended that a pi filter be used in both transmitter and receiver power supplies. emi and esd consideration source photonics? transceivers offer a metalized plasti c case and a special chassis grounding clip. as shown in the drawing, this clip connects the module case to chas sis 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 pr otection and helps reduce radiated emission from the module or the host circuit board through t he chassis faceplate. the attaching posts are at case potential and may be connected to chassis ground. they sh ould not be connected to circuit ground. plastic optical subassemblies are used to further reduc e 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 c able ferrule, the gigabit speed rf electrical signal is isolated from the connector area thus preventing radiated energy leaka ge from these surfaces to the outside of the panel.
