I

Channel-2 negative receiver input

– Negative side of channel-2 TMDS low voltage signal differential input pair.

Channel-1 positive receiver input

– Positive side of channel-1 TMDS low voltage signal differential input pair.

Rx1+

83

I

Channel-1 receives green pixel data in active display and CTL1 control signals in blanking.

Rx1-

84

I

Channel-1 negative receiver input

– Negative side of channel-1 TMDS low voltage signal differential input pair.

Channel-0 positive receiver input

– Positive side of channel-0. TMDS low voltage signal differential input pair.

Rx0+

86

I

Channel-0 receives blue pixel data in active display and HSYNC, VSYNC control signals in blanking.

Rx0-

87

I

Channel-0 negative receiver input

– Negative side of channel-0. TMDS low voltage signal differential input pair.

RxC+

89

I

Clock positive receiver input

– Positive side of reference clock. TMDS low voltage signal differential input pair.

RxC-

90

I

Clock negative receiver input

– Negative side of reference clock. TMDS low voltage signal differential input pair.

Sync detect

– Output to signal when the link is active or inactive. The link is considered to be active when DE is

actively switching. The TFP501 monitors the state DE to determine link activity. SCDT can be tied externally to PDO

SCDT

O

to power down the output drivers when the link is inactive.

High: Active link

Low: Inactive link

Output drive strength select

I

High : High drive strength

Low : Low drive strength

Staggered pixel select

– An active low signal used in the 2-pixel/clock pixel mode (PIXS = high). Time staggers the

even and odd pixel outputs to reduce ground bounce. Normal operation outputs the odd and even pixels

simultaneously.

High : Normal simultaneous even/odd pixel output

Low: Time staggered even/odd pixel output

Stresses beyond those listed under

"absolute maximum ratings" may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under

"recommended operating

conditions

" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
