The GT5940 PECL I/O module provides a bi-directional interface for PECL applications. The GT5940 is a plug-in module mounted onto the GT5150 or the GT5900. In addition to the 32 I/O channels, the GT5940 provides a conversion channel for a PECL external clock signal.

Architecture

The GT5940 PECL translation module employs eight MC10H350 differential level converters to provide translation from PECL to TTL levels. Eight MC10H351 differential level shifters provide translation from TTL to PECL levels. SIP sockets allow users to install PECL terminators specific to their application.
