DESCRIPTION
RxC+
89
I
Clock positive receiver input. Positive side of reference clock T.M.D.S. low-voltage signal differential input
pair.
RxC−
90
I
Clock negative receiver input. Negative side of reference clock T.M.D.S. low-voltage signal differential input
pair.
SCDT
8
O
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 TFP503 monitors the state DE to determine link activity. SCDT can be tied externally to
PDO to power down the output drivers when the link is inactive.
High: active link
Low: inactive link
ST
3
I
Output drive strength select. Selects output drive strength for high- or low-current drive (see dc specifications
for IOH(D) and IOL(D) vs ST state).
High: high drive strength
Low: low drive strength
STAG
7
I
Staggered pixel select. An active low signal used in 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.

NOTES:
1. t(pixel) is the pixel time defined as the period of the RxC clock input. The period of the output clock, ODCK, is equal to t(pixel) when
in 1-pixel/clock mode and 2 t(pixel) when in 2-pixel/clock mode.
2. The TFP503 is internally optimized using a laser-trim process to precisely fix the single-ended termination impedance, RT
,
