The cross-correlation method allows phase-noise measurements of high-quality devices with very low noise levels, using reference sources with higher noise levels than the device under test. To implement this method, a phase-noise analyzer needs to compute the cross-spectral density, that is, the Fourier transform of the cross-correlation, of two time series over a wide frequency range, from fractions of Hz to tens of MHz. Furthermore, the analyzer requires a high dynamic range to accommodate the phase noise of high-quality oscillators that may fall off by more than 100 dB from close-in noise to the noise floor at large frequency offsets. This paper describes the efficient implementation of a cross-spectrum analyzer in a low-cost FPGA, as part of a modern phase-noise analyzer with very fast measurement time.

In this paper, based on the programmable frequency dividers HMC394 and AD company's integer PLL chip ADF4107, in the premise of not reducing the phase detector frequency, improved the frequency resolution and effectively inhibits the phase stray. Designed a frequency source with high performance index: high resolution is 10kHz, low phase noise is-91.27dBc/Hz @10kHz, low spurious is less than-60dBc, high harmonic suppression is less than-60dBc,the design method is simple, low cost, flexible control, high performance and widely used.
