NOTES
1Timing specifications are measured with input levels of 3.0 V (V
IH) and 0 V (VIL) 0 for both 5 V and 3.3 V supplies.
2These maximum and minimum specifications are guaranteed over this range.
3Temperature range: T
MIN to TMAX: –40°C to +85 °C at 50 MHz and 140 MHz, 0 °C to +70°C at 240 MHz.
4Rise time was measured from the 10% to 90% point of zero to full-scale transition, fall time from the 90% to 10% point of a full-scale transition.
5Measured from 50% point of full-scale transition to 2% of final value.
6Guaranteed by characterization.
7f
CLK max specification production tested at 125 MHz and 5 V limits specified here are guaranteed by characterization.
8This power-down feature is only available on the ADV7127 in the TSSOP package.

NOTES:
1. OUTPUT DELAY (
t6) MEASURED FROM THE 50% POINT OF THE RISING
EDGE OF CLOCK TO THE 50% POINT OF FULL SCALE TRANSITION.
2. OUTPUT RISE/FALL TIME (
t7) MEASURED BETWEEN THE 10% AND
90% POINTS OF FULL SCALE TRANSITION.
3. TRANSITION TIME (
t8) MEASURED FROM THE 50% POINT OF FULL
SCALE TRANSITION TO WITHIN 2% OF THE FINAL OUTPUT VALUE.
