700MHz, Low Jitter, Crystal-to-3.3V LVPECL Frequency Synthesizer

NOTICE - The following device(s) are recommended alternatives:

The 84329B-01 is a general purpose, single output high frequency synthesizer and a member of the HiPerClockS™ family of High Performance Clock Solutions from IDT. The VCO operates at a frequency range of 250MHz to 700MHz. The VCO frequency is programmed in steps equal to the value of the crystal frequency divided by 16. 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 125kHz to 1MHz can be achieved using a 16MHz crystal depending on the output dividers.

Features

  • Fully integrated PLL, no external loop filter requirements
  • One differential 3.3V LVPECL output pair
  • Crystal oscillator interface
  • Output frequency range: 31.25MHz - 700MHz
  • VCO range: 250MHz - 700MHz
  • Parallel interface for programming counter and output dividers during power-up
  • Serial 3 wire interface
  • RMS period jitter: 5.5ps (maximum)
  • Cycle-to-cycle jitter: 35ps (maximum)
  • 3.3V supply voltage
  • 0°C to 70°C ambient operating temperature
  • For replacement device use 8T49N203A-dddNLG
