General Description

The ICS840004I is a 4 output LVCMOS/LVTTL Synthesizer optimized to generate Fibre Channel HiPerClockS™ reference clock frequencies and is a member of the HiPerClocksTM family of high performance clock solutions from ICS.

Using a 26.5625MHz, 18pF parallel resonant crystal, the following frequencies can be generated based on the 2 frequency select pins (F_SEL1:0): 212.5MHz, 159.375MHz, 156.25MHz, 106.25MHz, and 53.125MHz.

The ICS840004I uses ICS’ 3rd generation low phase ..

Key Features

  • Four LVCMOS/LVTTL outputs, 15Ω typical output impedance.
  • Selectable crystal oscillator interface or LVCMOS single-ended input.
  • Supports the following input frequencies: 212.5MHz, 159.375MHz, 156.25MHz, 106.25MHz and 53.125MHz.
  • RMS phase jitter @ 212.5MHz(2.55MHz - 20MHz): 0.49ps (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.
