Overview
The purpose of this document is to familiarize you with the DS91M040 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 primary function of the board is to assist system designers in development and analysis of M-LVDS clock
distribution networks in ATCA backplanes. The board also enables the user to examine performance and all
functions of the DS91M040 as a standalone device or in a point-to-point configuration.
The DS91M040 is a high-speed quad M-LVDS differential transceiver 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.
