DS91M040TSQ

The Texas Instruments DS91M040TSQ is a high-performance quad M-LVDS transceiver. It is engineered for driving and receiving clock or data signals across up to four multipoint networks. This transceiver supports a wide range of protocols including BLVDS, CML, LVDS, LVPECL, and M-LVDS, with a signaling rate of up to 250 Mbps.

Designed for demanding applications, the DS91M040TSQ operates within an industrial temperature range of -40°C to 85°C. It features 4 transmitters and 4 receivers, ensuring robust signal integrity. The device conforms to the TIA/EIA-899 M-LVDS standard and offers controlled transition times to minimize reflections in multipoint configurations.

Key electrical characteristics include a wide input common mode voltage range, allowing for up to ±1V of GND noise, and an 8 kV ESD rating on M-LVDS I/O pins for enhanced protection. The transceiver is housed in a compact 5 mm x 5 mm WQFN-32 package with a flow-through pinout, simplifying PCB layout and saving space.

This M-LVDS transceiver is suitable for multipoint and multidrop cable and backplane applications where increased drive current and noise margin are critical. Its design focuses on low jitter, low skew, and low power operation.
