addition to the skew presented be-
tween D+ and D- paired input pins.

signals
25 ps
Jitter budget for TMDS signals as
they pass through the level shier.
25ps = 0.056 at 2.25 Gbps
TMDS output oscillation elimination
e inputs already incorporate a squelch circuit. erefore, nothing is needed from application standpoint to eliminate TMDS output
oscillation when there is no TMDS input present. e IC will do this automatically.
