描述 Description

The Si3000?is a complete solution for voice I/O such as handsets in multi-function printers. It can be connected directly to any high-speed, ISOmodem system-side chip to support a telephone handset. An extended AT command set is available to control the Si3000. In addition to a codec (A/D, D/A), the device integrates a microphone preamplifier, three-input mixer, +12.5 to –34.5 dB of programmable gain, headphone/speaker driver, and an integrated handset hybrid for direct connection to a two-wire telephone handset.

簡(jiǎn)介

Si3000屬于集成電路（IC）的編解碼器。由制造生產(chǎn)的Si3000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。
