ICS8430252-45

Integrated

Circuit

Systems, Inc.

FEMTOCLOCKS™ C RYSTAL-TO-3.3V LVPECL

FREQUENCY SYNTHESIZER

GENERAL DESCRIPTION

FEATURES

The ICS8430252-45 is a 2 output LVPECL and

• One differential 3.3V LVPECL output and

One LVCMOS/LVTTL output

ICS

LVCMOS/LVTTL Synthesizer optimized to gen-

erate Ethernet reference clock frequencies and

is a member of the HiPerClocks™family of high

performance clock solutions from ICS. Using a

HiPerClockS™

• Crystal oscillator interface designed for a 25MHz,

18pF parallel resonant crystal

25MHz, 18pF parallel resonant crystal, the following frequen-

cies can be generated: 156.25MHz LVPECL output and,

125MHz LVCMOS output. The 8430252-45 uses ICS’ 3rd

generation low phase noise VCO technology and can achieve

1ps or lower typical rms phase jitter, easily meeting

Ethernet jitter requirements.The ICS8430252-45 is packaged

in a small 16-pin TSSOP package.

• A 25MHz crystal generates both an output frequency of

156.25MHz (LVPECL) and 125MHz (LVCMOS)

• VCO frequency: 625MHz

• RMS phase jitter @ 156.25MHz (1.875MHz - 20MHz) using

a 25MHz crystal: 0.46ps (typical)

• Full 3.3V supply mode

• 0°C to 70°C ambient operating temperature

• Industrial temperature available upon request
