V23806-S84-Z3 3.3 V V23806-S84-Z4 5V Testboard for ATM, ESCON, Fibre Channel and Gigabit Ethernet 1x9 Transceivers FEATURES • Allows for separate powering of receiver and transmitter section • Power supply lines filtered externally to module 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 fixture intended for use with the 1x9 pin row single mode 155MBd or 622MBd ATM transceiver, ESCON, Fibre Channel and Gigabit Ethernet transceivers. It provides a test medium for characterizing the performance of these transceivers. Figure 1.
