The DS92LV0421SQ/NOPB is a Texas Instruments serializer that converts 5 parallel LVDS inputs into a single CML serial output stream at up to 2.1 Gbps. The 2.1 Gbps data rate corresponds to a 10-to-75 MHz channel clock range — the serializer's PLL locks to the incoming parallel clock and serializes the five data channels into one differential pair, which sets the maximum cable length and jitter budget for the link.
The SN65LV1023ARHBT is a peer serializer but differs in key parametrics: it runs at 660 Mbps (vs 2.1 Gbps), uses LVTTL inputs (vs LVDS), and has 10 inputs (vs 5). The DS92LV0421SQ/NOPB will not drop into a board designed for the SN65LV1023ARHBT without a layout change — the supply voltages, input standard, and pinout differ.
