| 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 Figure 1. Application board (Top view) 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.
