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 enables the synchronous transmission of 28 bits of single-ended LVTTL data over five balanced-pair conductors, making it suitable for various display applications. The device operates from a single 3.3-V supply and is characterized for operation over ambient air temperatures of –40°C to 85°C.
