CS42426-CQZ集成電路（IC）的編解碼器規(guī)格書(shū)PDF中文資料

CS42426-CQZ屬于集成電路（IC）的編解碼器。由凌云邏輯制造生產(chǎn)的CS42426-CQZ編解碼器編解碼器是用于通過(guò)壓縮和解壓縮來(lái)轉(zhuǎn)換數(shù)據(jù)的半導(dǎo)體器件。數(shù)據(jù)壓縮可提高傳輸速度并減少存儲(chǔ)空間。某些編解碼器提供高達(dá) 32 位的分辨率，并且分別提供多達(dá) 6 個(gè)或 8 個(gè)模數(shù)轉(zhuǎn)換器和數(shù)模轉(zhuǎn)換器。除三角積分調(diào)制外，還有 I2C、I2S、SPI、串行、HDA、S/DIF、PCM、USB、AC'97 和 SLIMbus 數(shù)據(jù)接口。

General Description

The CS42426 CODEC provides two analog-to-digital and six digital-to-analog Delta-Sigma converters, as well as an integrated PLL, in a 64-pin LQFP package. The CS42426 integrated PLL provides a low-jitter system

clock. The internal stereo ADC is capable of independent channel gain control for single-ended or differential analog inputs. All six channels of DAC provide digital volume control and differential analog outputs. The general purpose outputs may be driven high or low, or mapped to a variety of DAC mute controls or ADC overflow indicators.
