LVDS driver for high-speed backplane and cable interfaces
The Texas Instruments DS90LV031ATMX/NOPB is a 4-channel LVDS driver in a 16-SOIC package, delivering 400 Mbps per channel over differential pairs. It translates CMOS/TTL inputs into low-voltage differential signals, keeping the edge rates controlled and the common-mode voltage within the LVDS standard for reliable reception at the far end. The 4/0 driver/receiver count means it is a pure transmit-side device — the companion receiver (DS90LV032 or similar) handles the return path.
Active production and compliance standing
ROHS3 compliant per the lead-free finish and the NOPB suffix, so it passes the EU RoHS directive without an exemption claim. The base product number DS90LV031 covers the SOIC, TSSOP, and LLP variants; the TMX suffix and /NOPB flag the Tape & Reel packaging and the green molding compound.
Board-fit and signal-integrity note
The 16-SOIC (0.154-inch body width, 3.90 mm) footprint is a standard JEDEC MS-012 outline — no exotic pad geometry. Surface-mount assembly with a typical reflow profile for lead-free solder; the package is MSL 1 per TI's standard handling. The 400 Mbps data rate translates to a 200 MHz fundamental frequency on the LVDS pair; keep the differential trace impedance at 100 Ω ±10 % and the stub length under 5 mm from the output pin to the via or connector. The driver's output common-mode voltage is internally biased to 1.2 V, so no external resistor divider is needed at the load — the receiver's internal termination handles the bias.
