DisplayPort 1.2
ESD & Overcurrent Protection

CDDFN10-0524P
Objective
Compliance
DisplayPort is a royalty-free alternative to
HDMI. DisplayPort 1.2 uses 3.3 V differential
digital signals that support 1, 2, or 4 differential
data pairs (lanes) in a main link. Each lane can
operate up to 540 Mhz and deliver 4.32 Gbit/s.
This solution provides DisplayPort interface
protection from ESD damage and short
circuits typically due to cables being plugged
and unplugged frequently.
