ESCRIPTION
The 8430252-45 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
output and, 125MHz LVCMOS output. The 8430252-45 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 8430252-45 is packaged in a small 16-pin
TSSOP package.
