ICS84025 - CRYSTAL-TO LVCMOS/LVTTL FREQUENCY SYNTHESIZER

Description

The ICS84025 is a Crystal-to-LVCMOS/LVTTL Frequency Synthesizer with Fanout Buffer and HiPerClockS™ a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS.

The VCO frequency is programmed in steps equal to the value of the crystal frequency.

Features

  • 6 LVCMOS/LVTTL outputs.
  • Crystal oscillator interface.
  • Output frequency range: 53.125MHz to 125MHz.
  • Crystal input frequency: 25MHz and 25.5MHz.
  • RMS phase jitter at 106.25, using a 25.5MHz crystal (637KHz to 10MHz): 3.25ps.
  • Phase noise: Offset Noise Power 100Hz -100 dBc/Hz 1KHz -115 dBc/Hz 10KHz -125 dBc/Hz 100KHz -127 dBc/Hz.
  • 3.3V core, outputs may either be 3.3V, 2.5V or 1.8V.
  • 0°C to 70°C ambient operating temperature.
