Quad LVDS line driver for high-speed serial links
The SN65LVDS31DR is a quad LVDS driver handling 400 Mbps per channel.
400 Mbps and the signal-integrity budget
At 400 Mbps the output edge rates are fast enough that PCB layout matters — keep the differential pair impedance controlled and the trace length mismatch small to avoid common-mode conversion.
Supply rail and power sequencing
The driver powers up with the outputs in a high-impedance state until the supply is stable, which avoids glitching the bus during power-on sequencing.
