Overview
The DS92LV16TVHGX/NOPB is a 16-bit bus LVDS (Low Voltage Differential Signaling) serializer/deserializer (SERDES) produced by Texas Instruments. This component transparently translates a 16-bit parallel bus into a BLVDS serial stream with embedded clock information, simplifying the transfer of data over PCB traces and cables. It operates within a frequency range of 25 to 80 MHz, achieving a full duplex throughput of 2.56 Gbps. The device is packaged in an 80-pin LQFP (PN) package and supports an industrial temperature range of -40°C to 85°C.
