FEMTOCLOCKS™CRYSTAL-TO-

3.3V, 250MHZ LVPECL CLOCK GENERATOR

PRELIMINARY

GENERAL DESCRIPTION

The ICS843023 is a Gigabit Ethernet Clock

Generator and a member of the HiPerClocksTM

family of high performance devices from ICS. The

ICS843023 uses a 25MHz crystal to synthesize

250MHz.The ICS843023 has excellent phase jitter

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

The ICS843023 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 25MHz,

18pF parallel resonant crystal

• Maximum output frequency: 250MHz, using a 25MHz crystal

• VCO range: 490MHz - 640MHz

• RMS phase jitter @ 250MHz, using a 25MHz crystal

(12KHz - 20MHz): 0.33ps (typical)

• 3.3V operating supply

• 0°C to 70°C ambient operating temperature
