ICS552-01A

Crystal Oscillator & Multiplier with 8 Low Skew Outputs

Description

The ICS552-01A produces 8 low skew

copies of a multiple of the input when a

clock or fundamental, parallel-mode crystal

is connected to it. Unlike other clock

drivers, it does not require a separate

oscillator for the input. Using a phase-

locked loop (PLL) to multiply the input

frequency, it is ideal for generating and

distributing multiple high frequency clocks.
