AC ELECTRICAL CHARACTERISTICS

(VEE = -2.0V to -3.6V, VCC = 2.375V to 3.6V, GND = 0, outputs terminated with 50

Ω ±1% to VCC - 2.0V. For SEL = high, CLK = high

or low, fIN = 2.0GHz. For SEL = low, FIN = 1.5GHz, CLK = 3.0GHz, input transition time = 125ps (20% to 80%), VIHD = VEE + 1.4V to

0, VILD = VEE to -0.2V, VIHD - VILD = 0.2V to the smaller of 3.0V or |VEE|. Typical values are at VEE = -3.3V, VCC = 3.3V, GND = 0, TA

= +25°C, VIHD = -0.9V, VILD = -1.7V, unless otherwise noted.) (Note 4)
