PCM3500EG4集成电路（IC）的编解码器规格书PDF中文资料

PCM3500EG4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PCM3500EG4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 PCM3500 is a low cost, 16-bit CODEC designed

for modem Analog Front End (AFE) and speech processing

applications. The PCM3500’s low power operation

from +2.7V to +3.6V power supplies, along

with an integrated power-down mode, make it ideal for

portable applications.

The PCM3500 integrates all of the functions needed for

a modem or voice CODEC, including delta-sigma

digital-to-analog and analog-to-digital converters, input

anti-aliasing filter, digital high-pass filter for DC

blocking, and an output low-pass filter. The synchronous

serial interface provides for a simple, or glue-free

interface to popular DSP and RISC processors. The

serial interface also supports Time Division Multiplexing

(TDM), allowing up to four CODECs to share a

single 4-wire serial bus.
