1 The min/max specifications are guaranteed over this range. The min/max values are typical over 4.75 V to 5.25 V range.
2 Ambient temperature range TMIN to TMAX: 40°C to +85°C. The die temperature, TJ, must always be kept below 110°C.
3 TTL input values are 0 V to 3 V, 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.
4 Guaranteed by characterization
5 Output delay measured from the 50% point of the rising edge of CLOCK to the 50% point of full-scale transition.
6 Pixel port consists of the following:
Pixel inputs:
P15–P0
Pixel controls:
HSYNC, FIELD/VSYNC, BLANK
Clock input:
