Resources for 843N252-45
Description
The 843N252-45 is a 1 LVPECL and 1 LVCMOS output synthesizer optimized to generate Ethernet reference clock frequencies. The device uses our fourth generation FemtoClock ® NG technology for an optimum of high clock frequency and low phase noise performance, combined with low power consumption and high power supply noise rejection. Using a 25MHz parallel resonant crystal, the following frequencies can be generated: 156.25MHz and 125MHz. With a very low phase noise VCO it is targeted to achieve 0.4ps or lower typical rms phase jitter, easily meeting Ethernet jitter requirements. The 843N252-45 is packaged in a small 16-pin TSSOP package.
