NOTES

1The max/min specifications are guaranteed over this range. The max/min values are typical over 4.75 V to 5.25 V range.

2Temperature range T

MIN to TMAX: 0 °C to +70 °C.

3TTL input values are 0 to 3 volts, with input rise/fall times

≤ 3 ns, measured between the 10% and 90% points. Timing reference points at 50% for inputs and

outputs. Analog output load

≤ 10 pF.

4Guaranteed by characterization.

5Output delay measured from the 50% point of the rising edge of CLOCK to the 50% point of full-scale transition.

6Pixel Port consists of the following:

Pixel Inputs:

P7–P0

Pixel Controls:

HSYNC, FIELD/VSYNC, BLANK, VSO, CSO_HSO, CLAMP

Clock Input:

CLOCK

7Teletext Port consists of the following:

Teletext Output:

TTXREQ

Teletext Input:

TTX
