AC Electrical Characteristics
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 = 475 (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 CLK and CLK are equal.
5 CLK and CLK pins are tri-stated when OE is Low asserted. CLK and CLK are driven differential when OE is High
unless its PD = low.
