REV. PrD 01/22/02
For the AD9244-65 only, with duty cycle stabilizer enabled. DCS function not applicable for -40 model.
Output delay is measured from clock 50% transition to data 50% transition, with 5pF load on each output.
Wake-up time is dependent on value of decoupling capacitors, typical values shown with 0.1 F and 10 F capacitors on REFT and REFB.
The clock period may be extended to 2 s with no degradation in specified performance at +25°C.
