Integrated Circuit Systems, Inc. ICS84330C 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 Pin compatible with the MC12430 Lead-Free package available Industrial temperature information available upon request GENERAL DESCRIPTION The ICS84330C is a general purpose, single output high frequency synthesizer and a member of HiPerClockS™ the HiPerClockS™ family of High Performance 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.
