Description
Port A High Speed inputs
Port B High Speed inputs
Port C High Speed inputs
HPD open-drain outputs for each port. Logic will follow
truth table on page 7.
External 1Kohm pull-up to 5V is required
5.0V voltage rail from HDMI/DVI connector. Used during
standby-mode.
GP I/O pin from SCALAR. Internal 100Kohm pull-down.
I 2 C signals for DDC communication on TMDS ports
4-differential high speed Output signals
3.3V Power Supply
Ground.
Output enable (Active LOW). When HIGH, all outputs are
Hi-Z and chip is placed into Standby Mode. Under Standby
Mode, the current supply is from VDD50.
