Overview
The SN65MLVD207DR is a multipoint-low-voltage differential (M-LVDS) line driver and receiver produced by Texas Instruments. This component is designed to operate at signaling rates up to 200 Mbps and complies with the M-LVDS standard TIA/EIA-899 for multipoint data interchange. It is optimized for applications requiring high-speed data transmission over multipoint buses, such as backplane or cabled data and clock transmission.
