Integrated Device Technology FemtoClock,Crystal-to-LVCMOS/LVTTL Frequency Synthesizer 840002AG-01LF

The 840002-01 is a two output LVCMOS / LVTTL Synthesizer optimized to generate Ethernet reference clock frequencies. Using a 25MHz 18pF parallel resonant crystal, the following frequencies can be generated based on the two frequency select pins (F_SEL[1:0]): 156.25MHz, 125MHz, and 62.5MHz. The 840002-01 uses IDT 's 3RD generation low phase noise VCO technology and can achieve 1ps or lower typical random rms phase jitter, easily meeting Ethernet jitter requirements. The 840002-01 is packaged in a small 16-pin TSSOP package.
