Single-ended high

level output voltage

VDD-10mV

VDD

VDD+10mV V

VDD is the DC termination voltage

in the HDMI or DVI Sink. VDD is

nominally 3.3V

Single-ended low level

output voltage

VDD-600mV VDD-500mV VDD-400mV V

The open-drain output pulls down

from VDD.

VSWING

Single ended output

swing voltage

600

Swing down from TMDS termina-

tion voltage (3.3V ±10%)

IOFF

Single-ended current

in high-Z state

µA

Measured with TMDS outputs

pulled up to VDD Max _(3.6V)

through 50Ω resistors.

TSKEW-INTRA

Intra-pair differential

skew

This differential skew budget is in

addition to the skew presented be-

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

100

This lane-to-lane skew budget is in

addition to skew between differen-

tial input pairs

TJIT

Jitter added to TMDS

signals

Jitter budget for TMDS signals as

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.
