説明
The 8V43042 is a two-output LVPECL synthesizer optimized to generate low jitter reference clock sources. Using a 25MHz or 24MHz, 12pF parallel resonant crystal, it can generate 156.25MHz or 150MHz. The 8V43042 uses Renesas' third generation of low phase noise VCO technology and can achieve 1ps or lower typical RMS phase jitter, easily meeting Ethernet jitter requirements. The 8V43042 is packaged in a small 20-pin TSSOP package.
