Overview
The SN65LVDS105PW is a 1:4 Low-Voltage TTL (LVTTL) to Low-Voltage Differential Signaling (LVDS) clock fanout buffer produced by Texas Instruments. This device is part of the LVDS repeater family and is designed to meet or exceed the requirements of the ANSI EIA/TIA-644 standard. It operates from a single 3.3-V supply and is capable of transmitting data at speeds up to 400 Mbps or clock frequencies up to 400 MHz. The SN65LVDS105PW is particularly useful for point-to-point baseband data transmission over controlled impedance media, such as printed-circuit board traces, backplanes, or cables.
