ICS84330-01
700MHZ, LOW JITTER, CRYSTAL-TO-3.3V
DIFFERENTIAL LVPECL FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
ICS
The ICS84330-01 is a general purpose, single out-
put 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 200MHz 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. Out-
put frequency steps from 250KHz to 2MHz can be achieved
using a 16MHz crystal depending on the output divider setting.
FEATURES
Fully integrated PLL, no external loop filter requirements
1 differential 3.3V LVPECL output
Crystal oscillator interface range: 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
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
