CDB8420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的CDB8420評估和演示板及套件該系列產品提供了一種方便的方法，在經過驗證的實施環(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。對于數量特別多或類別獨特的器件類別(如 ADC、DAC 和開關模式電源)，評估平臺可組合為一個單獨的產品系列。

General Description

The CS8420 is a stereo digital audio sample rate converter (SRC) with AES3-type and serial digital audio inputs, AES3-type and serialdigital audio outputs, and includes comprehensive control ability via a 4-wire microcontroller port. Channel status and user data can be assembled in block-sized buffers, making read/modify/write cycles easy.
