EVAL-ADF4158EB1Z屬于開發(fā)板套件編程器的評估演示板及套件。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的EVAL-ADF4158EB1Z評估和演示板及套件該系列產(chǎn)品提供了一種方便的方法，在經(jīng)過驗(yàn)證的實(shí)施環(huán)境中評估某些重點(diǎn)器件的性能或特性。評估方法通常有完善的文檔說明，并且視乎具體情況由評估軟件提供支持。產(chǎn)品通常由印刷電路板組成，板上已裝有重點(diǎn)器件以及必要或有用的支持元器件，另外也可能包括其他組件，例如電纜或電源。對于數(shù)量特別多或類別獨(dú)特的器件類別(如 ADC、DAC 和開關(guān)模式電源)，評估平臺可組合為一個單獨(dú)的產(chǎn)品系列。

GENERAL DESCRIPTION

The ADF4158 is a 6.1 GHz, fractional-N frequency synthesizer with modulation and waveform generation capability. It contains a 25-bit fixed modulus, allowing subhertz resolution at 6.1 GHz. It consists of a low noise digital phase frequency detector (PFD), a precision charge pump, and a programmable reference divider. There is a sigma-delta (Σ-Δ) based fractional interpolator to allow programmable fractional-N division. The INT and FRAC registers define an overall N-divider as N = INT + (FRAC/225).
