GENERAL DESCRIPTION

FEATURES

The ICS840031I is an IEEE 1394b Clock • (1) LVCMOS/LVTTL output

ICS

Generator and a member of the HiPerClocks^TM

family of high performance devices from ICS.

The ICS840031I uses a 24.576MHz crystal to

synthesize 98.304MHz. The ICS840031I has

• Crystal oscillator interface designed for a 24.576MHz,

18pF parallel resonant crystal

HiPerClockS™

• Output frequency: 98.304MHz (typical)

• VCO range: 490MHz to 640MHz

excellent phase jitter performance, from 12KHz – 20MHz

integration range. The ICS840031I is packaged in a small

8-pin SOIC, making it ideal for use in systems with limited

board space.

• RMS phase jitter @ 98.304MHz, using a 24.576MHz crystal

(12KHz - 20MHz): 0.75ps (typical)

• RMS phase noise at 98.304MHz (typical)

100KHz ..............-132.9 dBc/Hz

• 3.3V core/1.8V output operating supply

• Lead-Free fully RoHS compliant

• -40°C to 85°C ambient operating temperature
