Overview
The SN65LVDS95DGGRQ1 is a high-performance LVDS (Low-Voltage Differential Signaling) serdes (serializer/deserializer) transmitter manufactured by Texas Instruments. This integrated circuit is designed to transmit 21 bits of single-ended LVTTL (Low-Voltage Transistor-Transistor Logic) data over four balanced-pair conductors. It features three 7-bit parallel-load serial-out shift registers, a 7× clock synthesizer, and four LVDS line drivers. The internal operation is synchronized with the rising edge of the input clock signal, ensuring efficient serial unloading of the data registers. The transmitter outputs three serial streams and a phase-locked clock via LVDS output drivers, making it suitable for high-speed data transfer applications with minimal external components and user intervention.
