V23826-H18-C363
Application Notes
This Application Note assumes Fiber Optic Transceivers using 5 V power supply and
SerDes Chips using 3.3 V power supply. It also assumes no 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.
V
Value of R1...R4 may vary as long as proper 50
termination to
or 100
differential
EE
is provided. The power supply filtering is required for good EMI performance. Use short
V
V
tracks from the inductor L1/L2 to the module
Rx/
Tx. Further Application Notes for
CC
CC
electrical interfacing are available upon request. Ask for Appnote 82.
V
We strongly recommend a
plane under the module for getting good EMI

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