DESCRIPTION

The SN65LVDS049 is a dual flow-through differential

line driver-receiver pair that uses low-voltage differen-

tial signaling (LVDS) to achieve signaling rates as high

as 400 Mbps. The TIA/EIA-644-A standard compliant

electrical interface provides a minimum differential out-

put voltage magnitude of 250 mV into a 100-Ω load and

receipt of signals with up to 1 V of ground potential

difference between a transmitter and receiver. The

LVDS receivers have internal failsafe biasing that

places the outputs into a known high state for uncon-

nected differential inputs.
