FEMTOCLOCKS™CRYSTAL-TO-3.3V, 2.5V

LVPECL CLOCK GENERATOR

GENERAL DESCRIPTION

The ICS843023I is a Gigabit Ethernet Clock

Generator and a member of the HiPerClocksTM

family of high performance devices from ICS.

The ICS843023I uses a 25MHz crystal to

synthesize 250MHz. The ICS843023I has

excellent phase jitter performance, over the 1.875MHz – 20MHz

integration range. The ICS843023I 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

• Output frequency range: 245MHz - 320MHz

• VCO range: 490MHz - 640MHz

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

(1.875MHz - 20MHz): 0.39ps (typical)

Phase noise:
