843004-125数据手册Renesas中文资料规格书

描述 Description

The 843004-125 is a 4 output LVPECL Synthesizer optimized to generate Ethernet reference clock frequencies and is a member of the family of high performance clock solutions from IDT. The 843004-125 uses IDT's 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.
