FEMTOCLOCKS™CRYSTAL-TO-

3.3V LVPECL CLOCK GENERATOR

GENERAL DESCRIPTION

The ICS843021 is a Gigabit Ethernet Clock

Generator and a member of the HiPerClocksTM

family of high performance devices from ICS. The

ICS843021 uses a 25MHz crystal to synthesize

125MHz.The ICS843021 has excellent phase jitter

performance, over the 1.875MHz – 20MHz integration range.

The ICS843021 is packaged in a small 8-pin TSSOP, making it

ideal for use in systems with limited board space.

FEATURES

• 1 differential 3.3V LVPECL output

• Crystal oscillator interface designed for 22.4MHz - 28MHz,

18pF parallel resonant crystal

• Output frequency range: 112MHz - 140MHz

• VCO range: 560MHz to 700MHz

• Output duty cycle range: 49% - 51%

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

(1.875MHz - 20MHz): 0.37ps (typical)

• RMS phase noise at 125MHz (typical)
