Overview
The SN65LVDS95 is a Low-Voltage Differential Signaling (LVDS) serializer/deserializer (serdes) transmitter produced by Texas Instruments. This integrated circuit contains three 7-bit parallel-load serial-out shift registers, a 7× clock synthesizer, and four LVDS line drivers. It is designed to transmit 21 bits of single-ended LVTTL (Low-Voltage Transistor-Transistor Logic) data synchronously over four balanced-pair conductors, making it suitable for point-to-point subsystem communication with very low electromagnetic interference (EMI).
