The Texas Instruments SN65LVDS179 devices are differential line drivers and receivers that use low-voltage differential signalling (LVDS) to achieve signalling rates as high as 400 Mbps. The TIA/EIA-644 standard-compliant electrical interface provides a minimum differential output voltage magnitude of 247 mV into a 100-Ω load and receipt of 100-mV signals with up to 1 V of ground potential difference between a transmitter and receiver.

LVDS Communication

Low Voltage Differential Signaling, or LVDS, is an electrical signaling system that can run at very high speeds over cheap, twisted-pair copper cables.

Applications: Firewire, SATA, SCSI
