630 Mbps per channel — LVDS link budget for short-reach serial
The SN75LVDS391PW is a 4-channel LVDS driver from Texas Instruments, each channel rated for 630 Mbps. At that data rate the differential swing stays within the LVDS standard 350 mV typical, keeping EMI low across a point-to-point link up to about 10 meters on twisted-pair or PCB trace. It is a unidirectional driver only — 4 drivers, 0 receivers — so the signal path is one-way from the source to a separate LVDS receiver at the far end. The 3.0–3.6 V single supply rail matches the common 3.3 V LVDS ecosystem without needing an additional regulator.
16-TSSOP footprint and commercial temperature range
The surface-mount package requires standard reflow soldering; no exposed thermal pad, so thermal management relies on the board copper and airflow. This covers office equipment, consumer electronics, and indoor networking gear, but not extended industrial or automotive environments where -40 °C to +85 °C or wider is needed.
Active lifecycle and compliance — no end-of-life pressure
The base product number is 75LVDS391, indicating this is the commercial temperature variant.
