DATASHEET

GENERAL DESCRIPTION

FEATURES

The 8430252I-45 is a 2 output LVPECL and LVCMOS/LVTTL

Synthesizer optimized to generate Ethernet reference clock

frequencies. Using a 25MHz, 18pF parallel resonant crystal, the

following fre-quencies can be generated: 156.25MHz LVPECL

• One differential 3.3V LVPECL output and

One LVCMOS/LVTTL output

• Crystal oscillator interface designed for a 25MHz,

18pF parallel resonant crystal

output and, 125MHz LVCMOS output.The 8430252I-45 uses IDT’s

generation low phase noise VCO technology and can achieve

• A 25MHz crystal generates both an output frequency of

156.25MHz (LVPECL) and 125MHz (LVCMOS)

1ps or lower typical rms phase jitter, easily meeting Ethernet jitter

requirements. The 8430252I-45 is packaged in a small 16-pin

TSSOP package.

• VCO frequency: 625MHz

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

25MHz crystal: 0.39ps (typical)

• Full 3.3V supply mode

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

• Available in lead-free (RoHS 6) package
