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, R
R
= 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.
