DESCRIPTION

The SN65LVDS22 and SN65LVDM22 are differential

line drivers and receivers that use low-voltage

differential signaling (LVDS) to achieve signaling

rates as high as 400 Mbps. The receiver outputs can

be switched to either or both drivers through the

multiplexer control signals S0 and S1. This allows the

flexibility to perform splitter or signal routing functions

with a single device.

The TIA/EIA-644 standard compliant electrical

interface provides a minimum differential output

voltage magnitude of 247 mV into a 100-W load and

receipt of 100 mV signals with up to 1 V of ground

potential difference between a transmitter and

receiver. The SN65LVDM22 doubles the output drive

current to achieve LVDS levels with a 50-W load.
