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

The 843201-375 is a low phase-noise frequency margining synthesizer. In the default mode, the device nominally generates a 375MHz LVPECL output clock signal from a 25MHz crystal input. There is also a frequency margining mode available where the device can be configured, using control pins, to vary the output frequency up or down from nominal by 5%. The 843201-375 is provided in a 16-pin TSSOP package.

Features

  • One 375MHz nominal LVPECL output
  • Crystal oscillator interface designed for 25MHz, 18pF parallel resonant crystal
  • Output frequency can be varied ± 5% from nominal
  • VCO range: 700MHz - 800MHz
  • RMS phase jitter @ 375MHz, using a 25MHz crystal, (12kHz - 20MHz): 0.72ps (typical) @ 3.3V
  • Output supply modes
    Core/Output
    3.3V/3.3V
    3.3V/2.5V
    2.5V/2.5V
  • 0°C to 70°C ambient operating temperature
  • Available in lead-free (RoHS 6) package
