ICS84330CI

The ICS84330CI is a general purpose, single out-

put high frequency synthesizer and a member of

the HiPerClockS™ family of High Performance

Clock Solutions from ICS. The VCO operates at a

frequency range of 250MHz to 720MHz. The VCO

and output frequency can be programmed using the serial or

parallel interfaces to the configuration logic. The output can be

configured to divide the VCO frequency by 1, 2, 4, and 8. Output

frequency steps from 250KHz to 2MHz can be achieved using

a 16MHz crystal depending on the output divider setting.

• Fully integrated PLL, no external loop filter requirements

• 1 differential 3.3V LVPECL output

• Crystal oscillator interface: 10MHz to 25MHz

• Output frequency range: 31.25MHz to 720MHz

• VCO range: 250MHz to 720MHz

• Parallel or serial interface for programming M and N dividers

during power-up

• RMS Period jitter: 6ps (maximum)

• Cycle-to-cycle jitter: 40ps (maximum)

• 3.3V supply voltage

• -40°C to 85°C ambient operating temperature

• Pin compatible with the MC12430
