DESCRIPTION
The PCM4204 is a high-performance, four-channel analog-to-digital (A/D) converter designed for professional and broadcast audio applications. The PCM4204 architecture utilizes a 1-bit delta-sigma modulator per channel incorporating a novel density modulated dither scheme for improved dynamic performance. The PCM4204 supports 24-bit linear PCM output data, with sampling frequencies up to 216kHz. The PCM4204 can also be configured to output either 64x or 128x oversampled, 1-bit direct stream digital (DSD) data for each channel. In addition, the PCM4204 supports a DSD input mode, allowing 1-bit DSD to 24-bit PCM data format conversion utilizing the on-chip digital decimation filter. These features make the PCM4204 suitable for a variety of digital audio recording and processing applications. The PCM4204 includes a flexible audio serial port inter- face, which supports standard PCM audio data formats, as well as time division multiplexed (TDM) PCM data formats. Multiple format support allows the system designer to choose the interface format that best suits the end applica- tion. Audio data format selection, sampling mode configu- ration, and high-pass filter functions are all programmed using dedicated control pins. The PCM4204 operates from a +5V analog power supply and a +3.3V digital power supply. The digital I/O pins are compatible with +3.3V logic families. The PCM4204 is available in a thermally-enhanced HTQFP-64 PowerPAD package. PowerPAD is a registered trademark of Texas Instruments.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof.

Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic”are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use.
