Specifications subject to change without notice.
Wake-up time is dependent on the value of the decoupling capacitors; typical values shown with 0.1 µF and 10 µF capacitors on REFT and REFB.
The AD9248-65 model has a duty cycle stabilizer circuit that, when enabled, corrects for a wide range of duty cycles (see TPC 20).
Output delay is measured from CLOCK 50% transition to DATA 50% transition, with a 5 pF load on each output.
