Multimode 850 nm Gigabit Ethernet/Fibre Channel 1x9 Transceiver,
DC/DC Version
Figure 5
This Application Note assumes Fiber Optic Transceivers using 5 V power supply and
SerDes Chips using 3.3 V power supply. It also assumes self biasing at the receiver data
inputs (RD+/RD–) of the SerDes chip. Refer to the manufacturer data sheet for other
applications. 3.3 V-Transceivers can be directly connected to SerDes-Chips using
standard PECL Termination network.
Value of R1 may vary as long as proper 50
termination to
V
EE
or 100
differential is
provided. The power supply filtering is required for good EMI performance. Use short
tracks from the inductor L1/L2 to the module

The transceiver contains an automatic shutdown circuit. Reset is only possible if the
power is turned off, and then on again. (

Design criterion of the capacitor used is the resonant
frequency and its value must be in the order of the nominal
data rate. Short trace lengths are mandatory.
