FemtoClock™ NG Crystal-To-HCSL Frequency Synthesizer

The 841N4830 is a 3 HCSL, 1 LVPECL and 2 LVCMOS output Synthesizer optimized to generate PCI Express reference clock frequencies. The device uses Renesas' fourth generation FemtoClock™ NG technology for synthesis of high clock frequency at very low phase noise. It provides low power consumption with good power supply noise rejection. Using a 25MHz, 12pF parallel resonant crystal, the following frequencies can be generated: 100MHz, 50MHz and 25MHz. Maximum rms phase jitter of 0.27ps, easily meets PCI Express jitter requirements. The 841N4830 is packaged in a small 32-pin VFQFN package.
