Recommended Circuit Schematic

The split-loaded terminations for ECL signals need to be located at the input of devices receiving those ECL signals.

The power supply ltering is required for good EMI performance. Use short tracks from the inductor L1/L2 to the module Rx Vcc and Tx Vcc.

A GND plane under the module is required for good EMI and sensitivity performance.

Signal Detect

The C-1XX-1250AC-FDFB-SLCX transceivers are equipped with LVTTL signal detect output. The standard LVTTL output eliminates the

need for a LVPECL to LVTTL level shifter in most applications.

Power Coupling

A suggested layout for power and ground connections is given in gure 3A below. 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 ber-optic receiver employs a very high gain, wide bandwidth transimpedance amplier. This amplier detects and amplies 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 mini-

mize 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 lter

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 ush 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.
