Overview
The SN65LVDS048APW is a quad differential line receiver produced by Texas Instruments, designed to implement the electrical characteristics of low-voltage differential signaling (LVDS). This device is optimized for high-speed data transmission and is compatible with the TIA/EIA-644 LVDS standard. It operates with a 3.3-V power supply, reducing power consumption and increasing switching speeds compared to traditional 5-V differential standards. The SN65LVDS048APW is suitable for point-to-point baseband data transmission over controlled impedance media such as printed-circuit board traces, backplanes, or cables.
