Product details

At 155 Mbps, each driver delivers a differential output swing of typically 350 mV into a 100 Ω termination, compliant with the LVDS standard (TIA/EIA-644). This data rate supports common serial protocols such as SPI-over-LVDS, Camera Link base configuration, and backplane interconnects up to several meters over twisted-pair or PCB traces. The 155 Mbps figure is the per-channel maximum; actual system margin depends on cable length, connector quality, and the receiver's input sensitivity. For a 10-meter cable run, expect to derate to roughly 100 Mbps to maintain a clean eye opening.

The driver inputs are 5V-tolerant, so they can interface with legacy 5V logic without external level shifters. This simplifies BOM integration in mixed-voltage designs common in industrial control panels and test equipment.

Frequently asked questions

What is the closest pin-compatible alternative to SN75LVDS31DR?

The DS90LV031A from Texas Instruments is a pin-compatible, higher-speed alternative (400 Mbps) in the same 16-SOIC package. For a drop-in replacement with identical data rate, the SN65LVDS31 (industrial temp) shares the same pinout.
