ICS84329B

The ICS84329B is a general purpose, single

output 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 700MHz. The VCO frequency is programmed in steps equal

to the value of the crystal frequency divided by 16. 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 as small as 125kHz to 1MHz

can be achieved using a 16MHz crystal depending on the

output dividers.

• Fully integrated PLL, no external loop filter requirements

• One differential 3.3V LVPECL output

• Parallel resonant crystal oscillator interface

• Output frequency range: 31.25MHz to 700MHz

• VCO range: 250MHz to 700MHz

• Parallel interface for programming counter

and output dividers during power-up

• Serial 3 wire interface

• RMS Period jitter: 5.5ps (maximum)

• Cycle-to-cycle jitter: 35ps (maximuml)

• 3.3V supply voltage

• 0°C to 70°C ambient operating temperature

• Available in both standard and lead-free RoHS compliant

packages
