AD9578 Datasheet, Analog Devices

Any output frequency precision synthesis 11.8 MHz to 919 MHz Better than 0.1 ppb frequency resolution Ultralow rms jitter (12 kHz to 20 MHz) <300 fs rms using integer syn.

FPGA-based jitter attenuators and low jitter PLLs Precision disciplined clocks and clock synthesizers Multirate clock sy.

The AD9578 is a programmable synthesizer intended for jitter attenuation and asynchronous clocking applications in high performance telecommunications, networking, data storage, serializer/deserializer (SERDES), and physical layer (PHY) applications..
