CS4207-CNZ集成電路（IC）的編解碼器規(guī)格書(shū)PDF中文資料

CS4207-CNZ屬于集成電路（IC）的編解碼器。由凌云邏輯制造生產(chǎn)的CS4207-CNZ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 CS4207 is a highly integrated multi-channel low power HD Audio Codec featuring 192 kHz DACs, 96 kHz ADCs, 192 kHz S/PDIFTransmitters and Receiver, Microphone pre-amp and bias voltage, and a ground centered Headphone driver. Based on multi-bit, delta-sigma modulation, it allows infinite sample rate adjustment between 32 kHz and 192 kHz.
