Texas Instruments (TI) today announced the introduction of a 24-bit audio codec that supports asynchronous operation, the PCM3060, which enables analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) to operate with independent clocks. In applications such as DVD/Blu-Ray/HD-DVD recorders, digital TVs, digital set-top boxes, and car navigation systems, audio signals are often decoded and encoded at different sampling rates. The introduction of PCM3060 satisfies the encoding and decoding of asynchronous audio. The needs of the device.

The PCM3060 also delivers high design flexibility and outstanding audio performance. For example, the DAC output can be configured as single-ended or differential to further improve noise immunity. The new codec allows designers to choose the right control method between three-wire SPI, two-wire I2C or hardware control depending on the application and system design requirements. In addition, if only one clock is required, the codec can also support the synchronous mode by internal settings, and the ADC or DAC clock can also be selected as the clock source in this mode.

Not only does the PCM3060 have low jitter sensitivity, but it also achieves a high signal-to-noise ratio of up to 105 dB, so even in asynchronous mode, applications and clock source jitter can be severe with excellent audio performance. Customers can further enhance their audio systems by connecting the PCM3060 to TI's TMS320C6xTM family of DSPs or stereo Class D audio power amplifiers such as the TPA3120. The new device also works with TI's broad portfolio of audio products such as line drivers, receivers, analog multiplexers, PurePathTM digital amplifiers, and digital audio processors.

The PCM3060 is available now in a 28-pin TSSOP lead-free package.

TI offers a wide range of fundamental support for simulation engineers, including training and seminars, design tools and utilities, technical documentation, evaluation boards, an online knowledge base, a product information hotline, and comprehensive sample supply services.
