FEMTOCLOCKS™CRYSTAL-TO-3.3V, 2.5V

125MHZ LVPECL CLOCK GENERATOR

PRELIMINARY

GENERAL DESCRIPTION

The ICS843021I-01 is a Gigabit Ethernet Clock

Generator and a member of the HiPerClocksTM

family of high performance devices from ICS. The

ICS843021I-01 uses a 25MHz crystal to

synthesize 125MHz. The ICS843021I-01 has

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

integration range. The ICS843021I-01 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: 125MHz, using a 25MHz crystal

• VCO range: 490MHz - 640MHz

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

(1.875MHz - 20MHz): 0.41ps (typical) (for 3.3V)

• Full 3.3V or 2.5V operating supply

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