FEATURES
DESCRIPTION
The SN65LVDS4 is a single, low-voltage, differential
line receiver in a small-outline QFN package.
•
Designed for Signaling Rates up to:
500-Mbps Receiver
–
The signaling rate of a line is the number of voltage transitions that
are made per second expressed in the units bps (bits per second)
