Integrated Circuit Systems, Inc. ICS84330-02 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 Crystal oscillator interface: 10MHz to 25MHz Output frequency range: 31.25MHz to 700MHz VCO range: 250MHz to 700MHz Parallel or serial interface for programming M and N dividers during power-up RMS Period jitter: 5ps (maximum) Cycle-to-cycle jitter: 40ps (maximum) 3.3V supply voltage 0°C to 70°C ambient operating temperature Lead-Free package fully RoHS compliant Industrial temperature information available upon request GENERAL DESCRIPTION The ICS84330-02 is a general purpose, single output high frequency synthesizer and a HiPerClockS™ member of the HiPerClockS™ family of High Perfor mance Clock Solutions from ICS. The VCO operates at a frequency range of 250MHz to 700MHz. 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.
