PRELIMINARY

FEMTOCLOCKS™ CRYSTAL-TO-3.3V, 2.5V

LVPECL 400MHZ FREQUENCY SYNTHESIZER

ICS843801I-24

GENERAL DESCRIPTION

FEATURES

• One differential LVPECL output

The ICS843801I-24 is a 400MHz Frequency

ICS

Synthesizer and a member of the HiPerClocks^TM

family of high performance devices from ICS. The

ICS843801I-24 uses an 18pF parallel resonant

HiPerClockS™

• Crystal oscillator interface, 18pF parallel resonant crystal

(21.5625MHz - 25.3125MHz)

crystal over the range of 21.5625MHz

• Output frequency range: 172.5MHz - 202.5MHz, and

25.3125MHz. The ICS843801I-24 has excellent <1ps phase

jitter performance, over the 12kHz - 20MHz integration range.

The ICS843801I-24 is packaged in a small 8-pin TSSOP,

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

345MHz - 405MHz

• VCO range: 690MHz - 810MHz

• RMS phase jitter @ 400MHz, using a 25MHz crystal

(12kHz - 20MHz): 0.62ps (typical) @ 3.3V

• 3.3V or 2.5V operating supply

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

• Available in both standard and lead-free RoHS-compliant

packages
