General Description

The ICS840024I is a 4 output LVCMOS/LVTTL Synthesizer optimized to generate Ethernet HiPerClockS™ reference clock frequency and is a member of the HiPerClocksTM family of high performance clock solutions from ICS.

The ICS840024I uses ICS’ 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical random rms phase jitter, easily meeting Ethernet jitter requirements.

The ICS840024I is packaged in a small 20-pin TSSOP package.

Key Features

  • Four LVCMOS/LVTTL outputs, 15Ω typical output impedance.
  • Selectable crystal oscillator interface or LVCMOS single-ended input.
  • Supports the following output frequency: 125MHz.
  • RMS phase jitter @125MHz (1.875MHz - 20MHz): 0.60ps (typical).
  • Output supply modes: Core/Output 3.3V/3.3V 3.3V/2.5V 2.5V/2.5V.
  • -40°C to 85°C ambient operating temperature.
