CDB8952開發(fā)板套件編程器的評(píng)估演示板及套件規(guī)格書PDF中文資料

CDB8952屬于開發(fā)板套件編程器的評(píng)估演示板及套件。由凌云邏輯制造生產(chǎn)的CDB8952評(píng)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(píng)估某些重點(diǎn)器件的性能或特性。評(píng)估方法通常有完善的文檔說明，并且視乎具體情況由評(píng)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(duì)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(píng)估平臺(tái)可組合為一個(gè)單獨(dú)的產(chǎn)品系列。

Description

The CS8952 uses CMOS technology to deliver a highperformance, low-cost 100BASE-X/10BASE-T Physical Layer (PHY) line interface. It makes use of an adaptive equalizer optimized for noise and near end crosstalk (NEXT) immunity to extend receiver operation to cable lengths exceeding 160 m. In addition, the transmit circuitry has been designed to provide extremely low transmit jitter (
