Integrated Circuit Systems, Inc.
Electrical Characteristics - CPUCLK
Electrical Characteristics - CLK50, CLK66A0 & CLK66A1
Note 1: Guaranteed by design, not 100% tested in production.
Note 2: See timing diagrams for timing requirements.
Note 3: Input frequency should be measured at the REF output pin and tuned to ideal 25 MHz to meet ppm
frequency accuracy on PLL outputs.
Unless stated otherwise, VDD = 3.3 V+-5%, CL=20 pf, Ambient Temperature 0 to +70° C
