The SN65MLVD040 is a TI-produced 4-channel half-duplex M-LVDS line transceiver that meets the TIA/EIA-899 (M-LVDS) standard and is used to transmit and receive multipoint low-voltage differential signals. This device has independent enable pins that can control the driver output voltage transition time to improve signal quality.
The SN65MLVD040 is a 4‑channel half‑duplex M‑LVDS line transceiver that complies with the TIA/EIA‑899 (M‑LVDS) standard. It supports signaling rates up to 250 Mbps and is intended for high‑speed data and clock distribution over backplanes and cables in applications such as cellular base stations, network switches, and routers.
Key features include independent driver and receiver enables for listen‑while‑talking operation, low‑power high‑speed short‑reach performance, enhanced ESD protection, and a 48‑pin QFN package. The device operates from –40 °C to 85 °C and offers controlled transition times to reduce EMI and crosstalk.
