AD1939YSTZ Typical application Circuitry

AD1939YSTZ

The AD1939YSTZ is a high-performance, multichannel audio codec from Analog Devices, featuring integrated digital audio processing. It belongs to the AD1939 series, designed to deliver superior sound quality through high precision analog-to-digital (ADC) and digital-to-analog converters (DAC) combined with flexible digital signal processing. This codec is specifically tailored for professional and high-fidelity audio applications, such as digital mixing consoles, digital audio workstations, and multi-channel audio systems, where pristine audio quality and signal integrity are paramount.

1. Power Supply Voltage (AVDD, DVDD Pins): The AD1939YSTZ operates with two separate power supplies: an analog supply (AVDD) and a digital supply (DVDD). The analog supply voltage can range from 3.3V to 5V, while the digital supply voltage is typically 3.3V. This separation of power domains helps to minimize digital noise interference in the analog audio signals, ensuring high-quality audio reproduction. Proper decoupling and filtering at these pins are essential to maintain the device's performance.

2. Analog Audio Inputs and Outputs (AINx, AOUTx Pins): The device features multiple analog inputs (AINx) and outputs (AOUTx) for interfacing with external audio sources and destinations. These pins are directly connected to the integrated ADCs and DACs, providing high-fidelity audio signal conversion. The input and output channels must be properly configured and shielded to prevent cross-talk and maintain signal integrity.

3. Digital Audio Interface (Serial Data Ports - SDATA_INx, SDATA_OUTx, LRCLK, BCLK, and MCLK Pins): The AD1939YSTZ supports multiple serial data ports for digital audio input (SDATA_INx) and output (SDATA_OUTx), along with pins for the left/right word clock (LRCLK), bit clock (BCLK), and master clock (MCLK). These ports facilitate the transfer of digital audio data to and from the codec, supporting standard audio protocols such as I2S, TDM, and ADC Aux modes. Configuration of these interfaces is crucial for synchronization and accurate audio data transmission.

4. Control Interface (SPI Port - CS, SCLK, SDI, SDO Pins): The codec can be configured via a serial peripheral interface (SPI) consisting of chip select (CS), serial clock (SCLK), serial data input (SDI), and serial data output (SDO) pins. This interface allows for the adjustment of internal settings, such as volume control, sample rate settings, and input/output routing, enabling tailored audio processing to fit specific application requirements.

5. Clock Inputs (MCLKI, MCLKO Pins): The master clock input (MCLKI) pin is used to provide the primary clock signal to the codec, which is essential for the operation of the ADCs, DACs, and internal DSP engine. The MCLKO pin can output the master clock to other devices, allowing for clock synchronization in multi-device systems. The master clock frequency must be chosen based on the desired audio sample rates and system configuration.

6. Reset Pin (RESET Pin): The RESET pin is used to initialize the codec to its default state. This pin can be triggered upon power-up or used to reset the device in the event of a system error or configuration change. A proper reset sequence ensures the codec starts in a known configuration for reliable operation.

The AD1939YSTZ is a testament to Analog Devices' expertise in audio processing technology, offering not just exceptional audio quality but also a high degree of integration and flexibility for advanced audio systems. Its combination of high-quality ADCs, DACs, and configurable audio processing capabilities make it a versatile choice for designers looking to achieve professional-grade audio performance in their applications. Proper implementation of this codec, including careful consideration of power supply management, signal routing, and digital interface configuration, is essential for exploiting its full potential in delivering superior audio experiences.
