描述
The 843204I-01 is a 4 output LVPECL synthesizer optimized to generate Gigabit Ethernet and SONET reference clock frequencies. Using a 19.44MHz and 25MHz, 18pF parallel resonant crystal, 155.52MHz and 156.25MHz frequencies can be generated. The 843204I-01 uses our FemtoClock™ low phase noise VCO technology and can achieve 1ps or lower typical RMS phase jitter.
