概要
説明
The 843004-125 is a 4 output LVPECL Synthesizer optimized to generate Ethernet reference clock frequencies. The 843004-125 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 843004-125 is packaged in a small 24-pin TSSOP package.
