The 843204I 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 uses our FemtoClock™ low phase noise VCO technology and can achieve 1ps or lower typical RMS phase jitter. The 843204I is packaged in a 48-pin TSSOP package.
