PRELIMINARY

ICS840001-34

Integrated

Circuit

Systems, Inc.

FEMTOCLOCKS™ CRYSTAL-TO-

LVCMOS/LVTTL FREQUENCY SYNTHESIZER

GENERAL DESCRIPTION

FEATURES

The ICS840001-34 is a two output LVCMOS/ • (2) LVCMOS/LVTTL outputs, 20Ω typical output impedence

ICS

LVTTL Synthesizer and a member of the

HiPerClocks^TMfamily of high performance

devices from ICS. One output is the LVCMOS/

LVTTL main synthesized clock output (Q) and

(1) Main clock output (Q)

(1)Three-state reference clock output (REF_CLK)

HiPerClockS™

• Crystal oscillator interface can accept crystals from

15.3125MHz to 42.67MHz, 18pF parallel resonant crystal

one output is a three-state LVCMOS/LVTTL reference

clock (REF_CLK) output at the frequency of the crystal

oscillator. The device can accept crystal from 15.3125MHz

to 42.67MHz and can synthesize outputs from 81.67MHz

to 213.33MHz.The ICS840001-34 has excellent <1ps

phase jitter performance over the 637kHz – 10MHz

integration range. The ICS840001-34 is packaged in a

3mm x 3mm 16-pin VFQFN, making it ideal for use on

space constrained boards.

• Output frequency range: 81.67MHz to 213.33MHz

• VCO range: 490MHz to 640MHz

• RMS phase jitter @ 106.25MHz, using a 26.5625MHz crystal

(637kHz - 10MHz): 0.38ps (typical)

• 3.3V operating supply

• 0°C to 70°C ambient operating temperature
