Overview
The DS91M040TSQ/NOPB is a quad M-LVDS (Multipoint Low-Voltage Differential Signaling) transceiver designed by Texas Instruments. This component is specifically engineered for driving and receiving clock or data signals to and from up to four multipoint networks. It leverages M-LVDS technology, which is tailored for multipoint and multidrop cable and backplane applications, offering increased drive current to handle double terminations and minimizing reflections in multipoint configurations.
