OVERVIEW

The PM4541 T1XC EVBD evaluation daughterboard allows for the test, evaluation, and demonstration of the PMC PM4341 T1XC device. It is also compatible with the PM6341 E1XC device. This daughterboard can be used standalone with up to two T1XC devices but has been especially designed to mate with the PMC PM1501 EVMB evaluation motherboard to form a complete evaluation system. All required decoding logic is provided on the T1XC EVBD daughterboard to give the EVMB direct access to all registers of both T1XC devices.

All of the principal connections to both devices have been brought out to header strips for convenient test access. DS-1 digital interfaces are provided on a header strip and BNC or mini-bantam connectors are provided for DSX-1 analog signals. The backplane interfaces of each device are accessible through header strips and the devices can be interconnected back to back, effectively creating a jitterattenuating format converter (a function often implemented within a CSU) by dropping in shorting connectors into specific DIP sockets. Special considerations have been taken to ensure that the E1XC device will plug into one or both of the T1XC sockets.
