Single Mode 1300 nm Gigabit Ethernet/Fibre Channel 1x9 Transceiver,

DC/DC Version

Figure 5

Values of R1/2/3/4 may vary as long as proper 50

differential is provided. The power supply filtering is required for good EMI performance.

Use short tracks from the inductor L1/L2 to the module

V

GND plane under the module for getting good EMI performance.

The transceiver contains an automatic shutdown circuit. Reset is only possible if the

power is turned off, and then on again. (
