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.
