Codec goes asynchronous for flexible
clocking
Novel 24bit audio codec supports asynchronous operation, allowing the A/D convertor and D/A convertor to operate with independent clocks.
Texas Instruments has introduced a 24bit audio codec that supports asynchronous operation, allowing the A/D convertor and D/A convertor to operate with independent clocks In applications such as DVD/Blu-Ray/HD-DVD recorders, digital televisions, digital set-top boxes and car navigation systems, audio signals often need to be decoded and encoded at separate sampling rates, which drives the need for an asynchronous audio codec

RF platform brings three radios together
Texas Instruments has developed the industry's first solution that integrates mobile WLAN (mWLAN), Bluetooth and FM stereo audio all in a space-saving platform for mobile phones.
The PCM3060 also offers design flexibility and excellent audio performance.
For example, the DAC outputs can be configured as either single-ended or differential for better noise immunity.
The new codec enables designers to select the control method among modes of three-wire SPI, two-wire I2C or hardware control, depending on the application and system design requirements.
Additionally, the codec can be internally set to synchronous mode where either the ADC or the DAC clock can be selected as the clocking source when only one clock is required.
The PCM3060 has low jitter sensitivity and a high signal-to-noise ratio of 105dB to provide great audio performance, even in asynchronous mode and for applications or clocks sources with high jitter.
Customers can complete their audio system by interfacing the PCM3060 to a DSP such as TI's TMS320C6xT family of DSPs and to a stereo class-D audio power amplifier such as TI's TPA3120.
The new device also complements other products from TI's broad audio product portfolio including line drivers, receivers, analogue multiplexers, PurePath digital amplifiers and digital audio processors.
The PCM3060 is available now in a 28-pin TSSOP lead-free package and is priced at US $1.95 each in 1000-piece quantities.
