GENERAL DESCRIPTION
ICS
FEATURES
• Fully integrated PLL, no external loop filter requirements
• 1 differential 3.3V LVPECL output
The ICS84330-01 is a general purpose, single out-
put high frequency synthesizer and a member of
the HiPerClockS™ family of High Performance
Clock Solutions from ICS.TheVCO operates at a
frequency range of 200MHz to 700MHz.TheVCO
HiPerClockS™
• Crystal oscillator interface: 10MHz to 25MHz
• Output frequency range: 25MHz to 700MHz
• VCO range: 200MHz to 700MHz
• Parallel or serial interface for programming M and N dividers
during power-up
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. Out-
put frequency steps from 250KHz to 2MHz can be achieved
using a 16MHz crystal depending on the output divider setting.
• RMS Period jitter: TBD
• Cycle-to-cycle jitter: 15ps (typical)
• 3.3V supply voltage
• 0°C to 70°C ambient operating temperature
• Pin compatible with the SY89430V
