84330CVI Overview

IC synthesizer 720mhz 28-plcc

720MHz, Low Jitter, Crystal-to-LVPECL
Frequency Synthesizer
Data Sheet
84330CI
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
