84330CI

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...
