For the AD9245BCP-65 and AD9245BCP-80 models only, with duty cycle stabilizer enabled. DCS function not applicable for AD9245BCP-20 and AD9245BCP-40
models.
Output delay is measured from CLK 50% transition to DATA 50% transition, with 5 pF load on each output.
Wake-up time is dependent on value of decoupling capacitors; typical values shown with 0.1 μF and 10 μF capacitors on REFT and REFB.
