NOTES
1± 5% for 80 MHz and 66 MHz parts; ± 10% for 50 MHz and 35 MHz parts.
2Temperature Range (TMIN to TMAX); 0°C to +70°C.
3Numbers in parentheses indicate ADV471 parameter value.
4Clock and data feedthrough is a function of the amount of overshoot and undershoot on the digital inputs. For this test, the digital inputs have a 1 k resistor to
ground and are driven by 74HC logic. Glitch impulse includes clock and data feedthrough, –3 dB test bandwidth = 2 × clock rate.
5TTL 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 out-
puts. Analog output load 10 pF, D0–D7 output load 50 pF. See timing notes in Figure 2.
6DAC to DAC crosstalk is measured by holding one DAC high while the other two are making low to high and high to low transitions.
Specifications subject to change without notice.
