CDB4391開發(fā)板套件編程器的評估演示板及套件規(guī)格書PDF中文資料

CDB4391屬于開發(fā)板套件編程器的評估演示板及套件。由凌云邏輯制造生產(chǎn)的CDB4391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)過驗證的實施環(huán)境中評估某些重點器件的性能或特性。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的產(chǎn)品系列。

Description

The CS4391 is a complete stereo digital-to-analog system including digital interpolation, fourth-order deltasigma digital-to-analog conversion, digital de-emphasis, volume control, channel mixing and analog filtering. The advantages of this architecture include: ideal differential linearity, no distortion mechanisms due to resistor matching errors, no linearity drift over time and temperature and a high tolerance to clock jitter.
