Serial-port 16-bit Soundcomm Codec - Analog Devices

The AD1843 SoundComm Codec is a complete Analog front end for high performance DSP-based Telephony and Audio ap- plications. The device integrates the real-world Analog I/O re- quirements for many popular functions thereby reducing size, power consumption, and system complexity. The AD1843 SoundComm is the worlds first codec which CAN support four different sample rates simultaneously, without any beat fre- quency noise issues. This is essential for highly integrated Audio modem/fax products since the sample rates associated with au- dio are very much distinct from the sample rates associated with telephony-oriented data Communication It is also the first codec to offer on-chip digital phase lock loops for sample rate synchro- nization to external Clock signals. This sample rate flexibility is enabled through Analog Devices Continuous Time Oversampling (CTO) technology. The main elements of the AD1843 are its extensive input and mix- ing section, its two channels of sigma-delta () Analog-to-digital conversion, its four channels of digital-to-analog conversion, its digital Filters and the Clock and control circuitry for implementing the devices different modes. The AD1843 permits flexible sample- rate selection through programming and external synchronization, many input and output options, and many mixing options. By Analog Devices, Inc.
