Dallas, Tex.Texas Instruments Inc. has introduced a 24-bit audio codec that supports asynchronous operation, allowing the A/D converter and D/A converter to operate with independent clocks.
The PCM3060 asynchronous audio codec is aimed at systems in which audio signals often need to be decoded and encoded at separate sampling rates. Applications include DVD/Blu-Ray/HD-DVD recorders, digital TVs, digital set-top boxes and car navigation systems.
The PCM3060 offers design flexibility. The D/A converter outputs can be configured as either single-ended or differential for better noise immunity.
The PCM3060 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.
The PCM3060 codec can be internally set to synchronous mode where the A/D converter or the D/A converter 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 105 dB to provide high audio performance, even in asynchronous mode and for applications or clocks sources with high jitter.
Pricing: $1.95 each in 1,000-piece quantities.
Availability: Now in a 28-pin TSSOP lead-free package.
