NOTES
1
For the AD9235-65 model only, with duty cycle stabilizer enabled. DCS function not applicable for -20 and -40 models.
2
Output delay is measured from CLK 50% transition to DATA 50% transition, with 5 pF load on each output.
3
Wake-up time is dependent on value of decoupling capacitors; typical values shown with 0.1
μ
F and 10
μ
F capacitors on REFT and REFB.
