AC Electrical Characteristics - CLK0/CLK1, CLK0/CLK1

Unless stated otherwise, VDD=3.3 V ±10%, Ambient Temperature -40 to +85

°C

Note 2: Measurement taken from a single-ended waveform.

Note 3: Measurement taken from a differential waveform.

Note 4: Measured at the crossing point where instantaneous voltages of both CLK and CLK are equal.

Note 5: CLK pins are tri-stated when OE is low asserted. CLK is driven differential when OE is high.
