Integrated Device Technology FemtoClock Crystal-to-3.3V LVPECL Frequency Synthesizer 843004AG-01LFT

The 843004-01 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 . Using a 25MHz 18pF parallel resonant crystal, the following frequencies can be generated based on the settings of 2 frequency select pins (F_SEL[1:0]): 156.25MHz, 125MHz, 62.5MHz. The 843004-01 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 843004-01 is packaged in a small 24-pin TSSOP package.
