描述

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 frequencies can be generated: 156.25MHz LVPECL output and, 125MHz LVCMOS output. The 8430252I- 45 uses our third generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Ethernet jitter requirements. The 8430252I-45 is packaged in a small 16-pin TSSOP package.
