Overview

The Mod. N638 is a standard NIM module housing 16 independent logic level translators.
Each of the 16 channels accepts a NIM or an ECL signal and provides two NIM and one ECL outputs. The NIM and ECL inputs of each channel are ORed prior to fan-out.
The maximum operating frequency is 300 MHz.
Two couples of front panel input bridged connectors accept two COMMON IN NIM signals; each common signal allows the use of the module as a fan-out of 16 NIM and 8 ECL signals.
