Integrated Circuit Systems, Inc. ICS84329 700MHZ, LOW JITTER, CRYSTAL-TO-3.3V DIFFERENTIAL LVPECL FREQUENCY SYNTHESIZER FEATURES Fully integrated PLL, no external loop filter requirements 1 differential 3.3V LVPECL output Series resonant crystal oscillator interface Output frequency range: 25MHz to 700MHz VCO range: 200MHz 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 (maximum) 3.3V supply voltage 0°C to 70°C ambient operating temperature Lead-Free package fully RoHS compliant Pin compatible with the MC12429 GENERAL DESCRIPTION The ICS84329 is a general purpose, single output high frequency synthesizer and a member of the HiPerClockS™ HiPerClockS™family of High Performance Clock Solutions from ICS. The VCO operates at a frequency range of 200MHz 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.
