Analog Devices AD9574 is a programmable low jitter clock generator and frequency synthesizer ideal for high-performance communications, military, industrial, and test equipment applications. The device provides four differential LVPECL outputs, four differential LVDS outputs, and three 3.3-V/1.8-V CMOS outputs. The outputs can be independently programmed to generate frequencies from 10 MHz to 1.6 GHz with typical jitter below 100 fs RMS. The AD9574 also features a number of other advanced features, including:
- Integrated voltage regulators for power supply flexibility
- A programmable reference input for synchronization to an external clock source

Analog Devices AD9574 is a programmable low jitter clock generator and frequency synthesizer ideal for high-performance communications, military, industrial, and test equipment applications. The device provides four differential LVPECL outputs, four differential LVDS outputs, and three 3.3-V/1.8-V CMOS outputs. The outputs can be independently programmed to generate frequencies from 10 MHz to 1.6 GHz with typical jitter below 100 fs RMS. The AD9574 also features a number of other advanced features, including:
- Integrated voltage regulators for power supply flexibility
- A programmable reference input for synchronization to an external clock source
