Frequency Synthesizer
843252-45
Datasheet
General Description
The 843252-45 is a 2 LVPECL output Synthesizer optimized to
generate Ethernet reference clock frequencies. Using a 25MHz,
18pF parallel resonant crystal, the following frequencies can be
generated: 156.25MHz and 125MHz. The 843252-45 uses IDT’s 3
rd
generation low phase noise VCO technology and can achieve 1ps
or lower typical rms phase jitter, easily meeting Ethernet jitter
requirements. The 843252-45 is packaged in a small 16-pin TSSOP
package.
Features
Two differential LVPECL output pairs
Crystal oscillator interface designed for a 25MHz, 18pF parallel
resonant crystal
A 25MHz crystal generates output frequencies of: 156.25MHz
and 125MHz
VCO frequency: 625MHz
RMS Phase Jitter @ 156.25MHz, (1.875MHz – 20MHz) using a
25MHz crystal: 0.54ps (typical)
Full 3.3V supply mode
0°C to 70°C ambient operating temperature
Available in lead-free (RoHS 6) package
