ICS557-01

AC Electrical Characteristics - CLK/CLK

Unless stated otherwise, VDD=3.3 V ±5%, Ambient Temperature -40 to +85

°C

1 Test setup is R

L=50 ohms with 2 pF, RR = 475Ω (1%).

2 Measurement taken from a single-ended waveform.

3 Measurement taken from a differential waveform.

4 Measured at the crossing point where instantaneous voltages of both CLKOUT and CLKOUT are equal.

5 CLKOUT pins are tri-stated when OE is low asserted. CLKOUT is driven differential when OE is high.
