720MHz, Low Jitter, Crystal-to-LVPECL
Frequency Synthesizer
84330CI
Data Sheet
General Description
The 84330CI is a general purpose, single output high frequency
synthesizer. The VCO operates at a frequency range of 250MHz to
720MHz. 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 250kHz to 2MHz can be
achieved using a 16MHz crystal depending on the output divider
settings.
Features
• Fully integrated PLL, no external loop filter requirements
• One differential 3.3V LVPECL output
• Crystal oscillator interface: 10MHz to 25MHz
• Output frequency range: 31.25MHz to 720MHz
• VCO range: 250MHz to 720MHz
• Parallel or serial interface for programming M and N dividers
during power-up
• RMS period jitter: 6ps (maximum)
• Cycle-to-cycle jitter: 40ps (maximum)
• 3.3V supply voltage
• -40°C to 85°C ambient operating temperature
• Available in lead-free (RoHS 6) packages
