Overview
The SN65LVDS048A, produced by Texas Instruments, is a quad differential line receiver that implements the electrical characteristics of low-voltage differential signaling (LVDS). This device is designed to reduce power consumption, increase switching speeds, and operate with a 3.3-V supply rail. It is particularly useful for point-to-point baseband data transmission over controlled impedance media such as printed-circuit board traces, backplanes, or cables. The SN65LVDS048A is characterized for operation over an industrial temperature range of –40°C to 85°C and conforms to the TIA/EIA-644 LVDS standard.
