8430252-45 - Block Diagram
Description
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 frequencies can be generated: 156.25MHz LVPECL output and, 125MHz LVCMOS output. The 8430252-45 uses our 3rd 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.
