CS4272集成電路（IC）的編解碼器規(guī)格書PDF中文資料

CS4272屬于集成電路（IC）的編解碼器。由凌云邏輯制造生產的CS4272編解碼器編解碼器是用于通過壓縮和解壓縮來轉換數(shù)據(jù)的半導體器件。數(shù)據(jù)壓縮可提高傳輸速度并減少存儲空間。某些編解碼器提供高達 32 位的分辨率，并且分別提供多達 6 個或 8 個模數(shù)轉換器和數(shù)模轉換器。除三角積分調制外，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 CS4272 is a high-performance, integrated audio CODEC. The CS4272 performs stereo analog-to-digital (A/D) and digital-to-analog (D/A) conversion of up to 24-bit serial values at sample rates up to 192 kHz.

The D/A offers a volume control that operates with a 1 dB step size. It incorporates selectable soft ramp and zero crossing transition functions to eliminate clicks and pops.

The D/A’s integrated digital mixing functions allow a variety of output configurations ranging from a channel swap to a stereo-to-mono downmix.

Standard 50/15 μs de-emphasis is available for sampling rates of 32, 44.1, and 48 kHz for compatibility with digital audio programs mastered using the 50/15 μs pre-emphasis technique.
