TYPICAL OPERATING CHARACTERISTICS
= 3.0V to 3.6V; GND = 0V; T
AC characteristics are guaranteed by design and characterization. Tested using environment of Figure 6, 50
Measured with 100mVp-p noise (f 2MHz) on the power supply.
Deterministic jitter (D
This represents the skew on a QA and QB output with their inputs receiving the same signal.
