DC Electrical Characteristics

Unless stated otherwise, VDD = 3.3 V, Ambient Temperature -40 to +85

° C

AC Electrical Characteristics

Unless stated otherwise, VDD = 3.3 V, Ambient Temperature -40 to +85

° C

Notes:

1. Stresses beyond those listed in Absolute Maximum Ratings can permanently damage the device. Prolonged

exposure to levels above the operating limits but below the Absolute Maximum Ratings may affect device reliability.

2. With CLKIN = 160 MHz, FBIN to CLK4.

Using Spread Spectrum Input Clocks

The ICS574 uses IDT’s Spread Smart technology, allowing it to accurately track (pass through) any clocks that

implement spread spectrum techniques.
