5 V V23806-S84-Z3
3.3 V V23806-S84-Z4
Testboard for ATM, ESCON, Fibre Channel and
Gigabit Ethernet 1x9 Transceivers
FEATURES
•Allows for separate powering of receiver and transmitter sec-
tion
•Power supply lines filtered externally to mo dule under test
•Signal Detect level displayed by LED
•Power supply can be interrupted separately for receiver and
transmitter
•External Data and Signal Detect interfaces are made through
high performance SMA connectors
• Receiver data outputs are DC coupled. Output voltage can be
directly measured at SMA connectors
DESCRIPTION
This testboard is a functional test f ixture intended for use with
the 1x9 pin row single mode 155MBd or 622MBd ATM trans-
ceiver, ESCON, Fibre Channel and Gigabit Ethernet transcei v-
ers. It provides a test medium for characterizing the
performance of these transceivers.
