ICS83032I
75MHZ, 3RD OVERTONE OSCILLATOR
W/DUAL LVCMOS/LVTTL OUTPUTS
GENERAL DESCRIPTION
The ICS83032I is a SAS/SATA dual output
ICS LVCMOS/LVTTL oscillator and a member of the
HiPerClockS™ 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
www.DataSheeitd4eUa.clofmor 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

NOTE 1: Measured using Aeroflex PN9500.
NOTE 2: Measured using Wavecrest SIA-3000.
NOTE 3: Defined as skew between outputs at the same supply voltage and with equal load conditions.
Measured at VDD/2.
NOTE 4: These parameters are guaranteed by characterization. Not tested in production.
NOTE 5: This is the frequency error contributed by the oscillator and must be added to the frequency timing error from the
crystal to obtain the total frequency stability. See Frequency Stability in the Application Information Section.
