ICS83032I 75MHZ, 3 RD OVERTONE OSCILLATOR W/DUAL LVCMOS/LVTTL OUTPUTS PRELIMINARY GENERAL DESCRIPTION The ICS83032I is a SAS/SATA dual output LVCMOS/LVTTL oscillator and a member of the HiperClocks™ family of high performance de- vices from ICS. The ICS83032I uses a 3rd over- tone crystal to provide a reference frequency of 75MHz. The ICS83032I has excellent phase jitter perfor- mance, over the 900kHz - 7.5MHz integration range. The ICS83032I is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.

FEATURES

  • One LVCMOS/LVTTL output, 15Ω output impedence
  • Crystal oscillator interface designed for 3rd overtone 75MHz crystal
  • Output frequency range: 53MHz - 80MHz
  • RMS phase jitter @ 75MHz (900kHz - 7.5MHz): <125fs (typical)
  • 3.3V or 2.5V operating supply
  • -40°C to 85°C ambient operating temperature
  • Available in both standard and lead-free RoHS-compliant packages HiPerClockS™ ICS ICS83032I 8-Lead TSSOP 4.40mm x 3.0mm x 0.925mm package body G Package Top View OE XTAL_IN XTAL_OUT GND VDD nc BLOCK DIAGRAM PIN ASSIGNMENT 3rd Overtone Crystal Oscillator XTAL_IN XTAL_OUT OE Pullup 75MHz 75MHz The Preliminary Information presented herein represents a product in prototyping or pre-production.
