Description
The ICS552-01 produces 8 low-skew copies of the multiple input clock or fundamental, parallel-mode crystal. Unlike other clock drivers, these parts do not require a separate oscillator for the input. Using ICS’ patented Phase-Locked Loop (PLL) to multiply the input frequency, it is ideal for generating and distributing multiple high-frequency clocks. This is a single chip used for 3 different applications:

1) ICS552-01 (A mode) — an Oscillator mutilpier
2) ICS552-01 (B mode) — a Dual 1:4 buffer
3) ICS552-01 (C mode) — a 1:8 Oscillator buffer
