ICS840021I

FEMTOCLOCKS™ CRYSTAL-TO-

LVCMOS/LVTTL CLOCK GENERATOR

Integrated

Circuit

Systems, Inc.

GENERAL DESCRIPTION

FEATURES

The ICS840021I is a Gigabit Ethernet Clock • 1 LVCMOS/LVTTL output, 15Ω output impedence

ICS

Generator and a member of the HiPerClocks^TM

• Crystal oscillator interface designed for 25MHz,

family of high performance devices from ICS.The

18pF parallel resonant crystal

HiPerClockS™

ICS840021I uses a 25MHz crystal to synthesize

125MHz. The ICS840021I has excellent phase

• Output frequency: 125MHz

jitter performance, over the 1.875MHz – 20MHz integration

range. The ICS840021I is packaged in a small 8-pin TSSOP,

making it ideal for use in systems with limited board space.

• VCO range: 560MHz to 680MHz

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

(1.875MHz - 20MHz): 0.48ps (typical) (3.3V)

Offset

Noise Power

100Hz ............... -97.8 dBc/Hz

1kHz ..............-124.6 dBc/Hz

10kHz ..............-132.5 dBc/Hz

100kHz ..............-131.1 dBc/Hz

• Voltage supply modes:

V_DD/V_DDA= 3.3V

V_DD/V_DDA= 2.5V

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

• Lead-Free package fully RoHS compliant
