LOCKS™CRYSTAL

LVCMOS/LVTTL CLOCK

GENERATOR

GENERAL DESCRIPTION

FEATURES

The ICS840022 is a Gigabit Ethernet Clock • 1 LVCMOS/LVTTL output, 7Ω output impedence

ICS

Generator and a member of the HiPerClocks^TM

• Crystal oscillator interface designed for 25MHz,

family of high performance devices from ICS.

18pF parallel resonant crystal

HiPerClockS™

The ICS840022 uses a 25MHz crystal to

synthesize 125MHz or 62.5MHz.The ICS840022

• Output frequencies: 125MHz or 62.5MHz (selectable)

has excellent phase jitter performance, over the 1.875MHz –

20MHz integration range. The ICS840022 is packaged in a

small 8-pin TSSOP, making it ideal for use in systems with

limited board space.

• RMS phase jitter @ 125MHz, using a 25MHz crystal

(1.875MHz - 20MHz): 0.55ps (typical)

• RMS phase noise at 125MHz:

Offset

Noise Power

100Hz ..............-106.3 dBc/Hz

1KHz ..............-126.3 dBc/Hz

10KHz ..............-131.7 dBc/Hz

100KHz ..............-130.8 dBc/Hz

• 3.3V operating supply

• 0°C to 70°C ambient operating temperature

• Industrial temperature information available upon request
