PCM3000集成电路（IC）的编解码器规格书PDF中文资料

PCM3000属于集成电路（IC）的编解码器。由美国德州仪器公司制造生产的PCM3000编解码器编解码器是用于通过压缩和解压缩来转换数据的半导体器件。数据压缩可提高传输速度并减少存储空间。某些编解码器提供高达 32 位的分辨率，并且分别提供多达 6 个或 8 个模数转换器和数模转换器。除三角积分调制外，还有 I2C、I2S、SPI、串行、HDA、S/DIF、PCM、USB、AC'97 和 SLIMbus 数据接口。

DESCRIPTION

The PCM3000/3001 is a low-cost, single-chip stereo

audio codec (analog-to-digital and digital-to-analog

converter) with single-ended analog voltage input and

output.

Both ADCs and DACs employ delta-sigma modu-

lation with 64-times oversampling. The ADCs include

a digital decimation filter and the DACs include an

8-times oversampling digital interpolation filter. The

DACs also include digital attenuation, de-emphasis,

infinite zero detection and soft mute to form a

complete subsystem. The PCM3000/3001 operates

with left-justified, right-justified, I2S or DSP data

formats.

The PCM3000 can be programmed with a three-wire

serial interface for special features and data formats.

The PCM3001 can be pin-programmed for data

formats.

The PCM3000 and PCM3001 are fabricated using a

highly advanced CMOS process and are available in

a small 28-pin SSOP package. The PCM3000/3001

are suitable for a wide variety of cost-sensitive

consumer applications where good performance is

required.
