Overview
The ADF4001BCPZ-RL7 is a high-performance clock generator and phase-locked loop (PLL) synthesizer produced by Analog Devices, Inc. This device is designed to implement clock sources for PLLs that require very low noise and stable reference signals. It features a low noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider, and a programmable 13-bit N counter. The ADF4001 can be used to generate clocks for various applications requiring high frequency stability and low jitter.
