Overview
The purpose of this document is to familiarize you with the DS91M125 evaluation board, suggest the test setup
procedures and instrumentation, and to guide you through some typical measurements that will demonstrate the
performance of the device. The board enables the user to examine performance and all functions of the
DS91M125 as a standalone device.
The DS91M125 is a high-speed 1:4 M-LVDS repeater with an LVDS input designed for multipoint applications
with multiple drivers or receivers. The device conforms to TIA/EIA-899 standard. It utilizes M-LVDS technology
for low power, high-speed and superior noise immunity.
Description
