Austin, TX. Crystal Semiconductor today introduced the CS4226 surround sound codec. The CS4226 is the first single-chip codec to support Dolby Digital Surround (AC-3) and Dolby Pro Logic applications.

The CS4226 incorporates stereo A/D converters, six D/A converters (each with independent volume control), a mono A/D converter and an S/PDIF receiver. The A/D converters feature 95 dB dynamic range and the D/A converters perform to 108 dB signal-to-noise ratio and 98 dB dynamic range. A 3:1 multiplexer prior to the stereo A/D converter provides selection for three different stereo audio sources.

The on-chip S/PDIF receiver supports reception of both stereo PCM audio data and compressed 5.1 channel AC-3 and MPEG audio data. This capability enables the CS4226 receiver to directly connect to both CD players and DVD players with digital outputs. The receiver also contains selectable de-emphasis filters for 32 kHz, 44.1 kHz, and 48 kHz applications.

Crystal says its new part can replace as many as nine discrete, integrated circuits in an AC-3 home theater product. Competitive solutions typically consist of an input multiplexer, stereo A/D converter, three stereo D/A converters, three volume control devices, and a digital audio receiver IC.

“The CS4226 plus an external AC-3 decoder offers the highest integration solution currently available for combined Dolby Digital Sound and Dolby Pro Logic receiver applications,” commented Roger Dressler of Dolby Labs.

The CS4226 is available in a 44-pin thin quad flat pack. It is priced at $32.00 in quantities of 1,000. Samples are available now with production quantities planned for the fourth quarter of 1996.

Last week, Crystal introduced another single-chip audio sub-system, the CS4238B, which implements QSound® Labs’ QXpander™ technology.
