Overview
The SN65LVDS93A, produced by Texas Instruments, is a Low-Voltage Differential Signaling (LVDS) serializer/deserializer (SerDes) transmitter. This integrated circuit contains four 7-bit parallel load serial-out shift registers, a 7 × clock synthesizer, and five LVDS drivers. It is designed to transmit 28 bits of single-ended LVTTL (Low-Voltage Transistor-Transistor Logic) data over five balanced-pair conductors, making it suitable for various display applications.
