Overview
The SN65LVDS93DGGR is a Low-Voltage Differential Signaling (LVDS) serializer/deserializer (serdes) transmitter produced by Texas Instruments. This integrated circuit is designed to efficiently transmit large amounts of data over short distances with minimal electromagnetic interference (EMI). The SN65LVDS93 contains four 7-bit parallel-load serial-out shift registers, a 7× clock synthesizer, and five LVDS drivers, enabling the synchronous transmission of 28 bits of single-ended LVTTL data over five balanced-pair conductors. It is compatible with receivers such as the SN65LVDS94 and operates within an industrial temperature range of -40°C to 85°C.
