Overview
The SN75LVDS83A Flatlink™ Transmitter, produced by Texas Instruments, is a high-performance Low-Voltage Differential Signaling (LVDS) serializer designed for display applications. This device integrates four 7-bit parallel-load serial-out shift registers, a 7× clock synthesizer, and five LVDS line drivers. It enables the transmission of 28 bits of single-ended LVTTL data over five balanced-pair conductors, making it suitable for various display resolutions ranging from HVGA to HD.
