Typical Operating Characteristics (continued)

= 3.3V, OV

= 2.0V, GND = 0, REFIN = REFOUT (internal reference), C

REFOUT

= 0.1µF, C

≈ 5pF at digital outputs, V

= -0.5dBFS

differential input, DCE = high, CLKTYP = high, PD = low, G/T = low, f

CLK

= 65MHz (50% duty cycle), C

REFP

= C

REFN

= 0.1µF to GND, 1µF

in parallel with 10µF between REFP and REFN, C

COM

= 0.1µF in parallel with 2.2µF to GND, T

= +25°C, unless otherwise noted.)
