LVDS83BTSSOPEVM User’s Guide

The SN75LVDS83B FlatLink™ transmitter contains the following functions within a single integrated
circuit:

Four 7-bit, parallel-load, serial-out, shift registers

A 7x clock synthesizer

Five low-voltage differential signaling (LVDS) line drivers

These functions allow 28 bits of single-ended LVTTL data to be synchronously transmitted over five
balanced-pair conductors for receipt by a compatible receiver, such as the SN75LVDS82 and LCD panels
with integrated LVDS receivers.

This evaluation module (EVM) acts as a reference design that can be easily modified for any projected
application. Target applications include the following:

LCD panel drivers

Ultra-mobile PCs (UMPCs)

Netbook PCs

Digital picture frames

Schematics and layout information are included at the end of the manual.
