The split-load terminations for ECL signals need to be located at the input of devices receiving those ECL signals. The power supply filtering 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. EMI and ESD Considerations OIC 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 installed flush through the panel cutout. The grounding clip in this way 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 emissions 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 emissions 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 form the connector area thus preventing radiated energy leakage from these surfaces to the outside of the panel. 1.25 Gbps Singlemode SFF LC Transceiver C-13-1250/C-F-SLC * C-13-1250/C-F-SLC2 * C-13-1250/C-FDFB-SLC2 * C-15-1250/C-FDFB-SLC2 Package Diagram Units in mm (inch) .000 (0.400) 10.16 13.6 (0.520) (0.535) +0 -0.01 -0.008 13.20 0.594 15.08 (1.921) +0 -0.2 +.000 -(0.004) 48.8 6.97 (0.274 ) 13.50 (0.531 ) (0.039O 0.002) 1.78 (0.070) 17.78 9.80 (0.386) (0.386) 3.81 0.50 (0.020) 1.00O0.05 (0.086) (0.150) 11.36 10.50 (0.413) 9.8 9.50 (0.374) 3.95 (0. 447 ) (0.155 ) 7.12 5.08 6.25 (0.246) (0.280) (0.200) (0.700) Case with EMI Shielding Finger Recommended Board Layout Hole Pattern DIMENSION IN MILLIMETER (INCHES) NOTES: 1.THIS FIGURE DESCRIBE THE RECOMMENDED CIRCUIT BOARD LAYOUT FOR THE SFF TRANSCEIVER. 2.THE HATCHED AREAS ARE KEEP-OUT AREAS RESERVED FOR HOUSING STANDOFF.
