ICS840002-32 Datasheet Crystal-to Lvcmos/lvttl Frequency Synthesizer

Manufacturer: Integrated Circuit Systems

Overview: PRELIMINARY Integrated Circuit Systems, Inc. ICS840002-32 FEMTOCLOCKS™CRYSTAL-TOLVCMOS/LVTTL FREQUENCY.

General Description

The ICS840002-32 is a 2 output LVCMOS/ LVTTL Synthesizer optimized to generate HiPerClockS™ Fibre Channel or Serial ATA reference clock frequencies and is a member of the HiPerClocks TM family of high perfor mance clock solutions from ICS.

Using an 18pF parallel resonant crystal, the following frequencies can be generated based on 1 frequency select pin (SEL): 106.25MHz and 75MHz, or 212.5MHz.

The ICS840002-32 uses ICS’ 3 rd generation www.DataSheet4U.com low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Fibre Channel and Serial ATA jitter requirements.

Key Features

  • Two LVCMOS/LVTTL outputs, 15Ω typical output impedance.
  • Crystal oscillator interface.
  • Output frequency range: 75MHz and 106.25MHz, or 212.5MHz.
  • RMS phase jitter at 106.25MHZ (637kHz - 5MHz): 0.86ps (typical).
  • Full 3.3V or 3.3V core/2.5V output supply mode.
  • 0°C to 70°C ambient operating temperature.
