APPLICATION NOTE
Single Mode 155 MBd ATM 1x9 Transceiver
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 con-
nected to SerDes-Chips using standard PECL Termination
network.
Value of R1...R4 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 V
CC
Rx/V
CC
Tx. Further applica-
tion notes for electrical interfacing are available upon request.
Ask for Appnote 82.
We strongly recommend a V
EE
plane under the module for get-
ting good EMI performance.
The transceiver contains an automatic shutdown circuit. Reset
is only possible if the power is turned off, and then on again.
