ICS840004I-01 Datasheet Crystal-to Lvcmos/lvttl Frequency Synthesizer

Manufacturer: Integrated Circuit Systems

Overview: PRELIMINARY Integrated Circuit Systems, Inc. ICS840004I-01 FEMTOCLOCKS™CRYSTAL-TOLVCMOS/LVTTL FREQUENCY.

General Description

The ICS840004I-01 is a 4 output LVCMOS/LVTTL Synthesizer optimized to generate Ethernet HiPerClockS™ reference clock frequencies and is a member of the HiPerClocksTM family of high performance clock solutions from ICS.

Using a 25MHz, 18pF parallel resonant crystal, the following frequencies can be generated based on the 2 frequency select pins (F_SEL1:0): 156.25MHz, 125MHz, and 62.5MHz.

The ICS840004I-01 uses ICS’ 3rd generation low phase noise VCO technology and can ..

Key Features

  • Four LVCMOS/LVTTL outputs, 15Ω typical output impedance.
  • Selectable crystal oscillator interface or LVCMOS single-ended input.
  • Supports the following output frequencies: 156.25MHz, 125MHz and 62.5MHz.
  • RMS phase jitter @ 156.25MHZ (1.875MHz - 20MHz): 0.52ps (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.
