At 400 Mbps each driver channel delivers a 2.5 ns unit interval. For a 16-inch FR4 trace with ~2.7 ns/m propagation delay, the round-trip skew budget is tight — keep stub lengths under 0.5 inches and match differential pair lengths to within 50 mils. The driver's output swing (typically 350 mV into a 100 Ω termination) provides adequate noise margin for LVDS receivers with 100 mV threshold.
ROHS3 compliant.
Pin-compatible with standard SOIC-16 LVDS drivers
The SN65LVDS31MDREP shares the same 16-SOIC footprint and pinout as the commercial-temperature SN65LVDS31D. If your design already uses the SN65LVDS31D, the MDREP variant is a direct thermal upgrade for harsh environments without board changes.
