ICS9341

The ICS9341 is a kind of 133 MHz clock generator and integrated buffer for PowerPC. It generates all clocks required for high speed PowerPV RISC microprocessor systems. Generating clocks in phase with an external reference frequency. The device employs a proprietary closed loop design, which tightly controls the percentage of spreading over process and temperature variations.

There are some features of the ICS9341 as follows: (1)up to 133 MHz frequency support; (2)stop clocks for power management ; (3)spread spectrum for EMI control ±0.25% center spread; (4)generates the following system clocks: 4-CPUA (3.3 V, up to 133 MHz), 4-CPUB (3.3 V, up to 133 MHz), 8-PCI (3.3 V, 33.3 MHz), 1-OUT (3.3 V, 64 MHz), 1-OUT/2 (3.3 V, OUT/2 MHz) and 2-REF (3.3 V, 14.318 MHz).

What comes next is about the maximum ratings of the ICS9341: (1)support voltage: 7.0 V; (2)logic inputs: GND-0.5 to VDD+0.5 V; (3)ambient operating temperature: 0 to +70; (4)storage temperature: -65 to +150.
