VDD is the DC termination voltage
in the HDMI or DVI Sink. VDD is
nominally 3.3V

TSKEW-INTRA
Intra-pair differential
skew
This differential skew budget is in
addition to the skew presented be-
30
ps
tween D+ and D- paired input pins.
HDMI revision 1.3 source allowable
intrapair skew is 0.15 Tbit.
TSKEW-INTER
Inter-pair lane-to-lane
output skew
This lane-to-lane skew budget is in
100
ps
addition to skew between differen-
tial input pairs
TJIT
Jitter added to TMDS
signals
Jitter budget for TMDS signals as
25
ps
they pass through the level shifter.
25ps = 0.056 at 2.25 Gbps
TMDS output oscillation elimination
The inputs already incorporate a squelch circuit. Therefore, nothing is needed from application standpoint to eliminate TMDS output
oscillation when there is no TMDS input present. The IC will do this automatically.
