MAX9180EXT+T

Signal Buffers, Repeaters, Splitters Overview

The MAX9180EXT+T is a low-voltage differential signaling (LVDS) repeater manufactured by Analog Devices Inc./Maxim Integrated. It accepts a single LVDS input and duplicates the signal at a single LVDS output, operating from a single 3.3V supply with a typical supply current of 10mA. The device supports data rates up to 400Mbps and operates within an ambient temperature range of -40°C to +85°C. Key electrical parameters include a differential propagation delay of 2.8ns maximum, 23ps peak-to-peak added deterministic jitter, and 0.6ps RMS added random jitter. It features fail-safe circuitry that sets the output high for undriven, open, shorted, or terminated inputs.
