ICS84329

Integrated

Circuit

Systems, Inc.

700MH , LOW JITTER, CRYSTAL-TO-3.3V

IFFERENTIAL LVPECL FREQUENCY

SYNTHESIZER

GENERAL DESCRIPTION

FEATURES

The ICS84329 is a general purpose, single output • Fully integrated PLL, no external loop filter requirements

ICS

high frequency synthesizer and a member of the

HiPerClockS™ family of High Performance Clock

• Series resonant crystal oscillator interface

Solutions from ICS. The VCO operates at a fre-

• 1 differential 3.3V LVPECL output

HiPerClockS™

• Output frequency range: 25MHz to 700MHz

• VCO range: 200MHz to 700MHz

• Parallel interface for programming counter

and output dividers during power-up

quency range of 200MHz to 700MHz. The VCO

frequency is programmed in steps equal to the value of the

crystal frequency divided by 16.TheVCO 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.

• Serial 3 wire interface

• RMS Period jitter: 5.5ps (maximum)

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

• 3.3V supply voltage

• 0°C to 70°C ambient operating temperature

• Lead-Free package fully RoHS compliant

• Pin compatible with the MC12429
