OSCILLATOR, MULTIPLIER, AND BUFFER WITH 8 OUTPUTS
IDT™ / ICS™ OSCILLATOR, MULTIPLIER, AND BUFFER WITH 8 OUTPUTS 1
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 IDT’s
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 mutiplier
2) ICS552-01 (B mode) — a Dual 1:4 buffer
3) ICS552-01 (C mode) — a 1:8 Oscillator buffer

... The nominal impedance of the clock output Decoupling Capacitors As with any high-performance mixed-signal IC, the ICS552-01 must be isolated from system power supply noise to perform optimally. Decoupling capacitors of 0.01µF must be connected between each VDD and GND on pins 4 and 6, and 16 and 14. Other VDDs and GNDs can be connected to these pins or directly to their respective ground planes ...
