Description

The 843004I-156 is a 4 output LVPECL synthesizer optimized to generate Ethernet reference clock frequencies. Using a 25MHz 18pF parallel resonant crystal, the 843004I-156 can generate 156.25MHz.

The 843004I-156 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 843004I-156 is packaged in a small 24-pin TSSOP E-Pad package.
