Overview
The SN65LVDS93B is a Low-Voltage Differential Signaling (LVDS) serializer/deserializer (SerDes) transmitter produced by Texas Instruments. This device is designed to convert 28 bits of single-ended LVTTL (Low-Voltage Transistor-Transistor Logic) data into five balanced-pair LVDS outputs. It integrates four 7-bit parallel load serial-out shift registers, a 7 × clock synthesizer, and five LVDS drivers in a single integrated circuit. This allows for the synchronous transmission of data over long distances with minimal signal degradation, making it suitable for various display applications.
