CD chip adds MP3 to consumer players
The SAA7752 is a low-cost CD chip for a wide range of applications including today's increasingly popular Internet audio equipment such as MP3 CD players
A reference design is also available, incorporating a PCB with ICs and a software stack to provide the features required by the market, enabling manufacturers to cut development time and costs. The chip will drive down costs for the mass market and, accordingly is expected to increase market acceptance of MP3 CD players.

"MP3 has captured the imagination of consumers.
The key to what consumers want is flexibility, and MP3 offers exactly that: the ability to download music from the Internet, burn it to a CD and play it back in the living room, while on the move or in the car.
The CD offers tremendous storage capacity that has never been available before for audio content," said Paul O'Donovan, Senior Analyst with Gartner Dataquest.

"We expect MP3 playback on CD equipment to become the norm within two years.
This is a significant opportunity for semiconductor manufacturers operating in the audio CD market."
"We developed the SAA7752 with our mass-market customers in mind.
We created a reference design and software stack to shorten development time, reduce production risk and enable a quick time to market for our customers," said Hans Fleurkens, Product Marketing Manager, BL Audio Solutions for Audio DSP products at Philips Semiconductors.
"This fits with our objective to make audio portable for the end user and will further the demand for MP3 CD players by meeting high-volume consumer price points."
A single read/write CD can contain over ten hours of music in MP3 format.
Consumers can use a computer to legally download MP3 files from the Internet or to save their own music collection in a different format, condensing their entire audio catalogue onto a handful of CDs using the MP3 format.
The SAA7752 offers advanced digital signal processing, enhanced functionality and interfacing on a single chip, targeted for MP3CD solutions, and is the ideal companion to CD servo ICs.
A solution based on the SAA7752 requires only a small number of external components, allows for slimline designs and lowers the overall system costs.
Reference designs and ready to use software stacks minimise development costs for Philips' customer base.
The SAA7752 is one of the products in the SAA775x DSP family of audio ICs.
All the SAA775x ICs have a programmable architecture enabling support for all popular audio decompression algorithms such as MP3, AAC and WMA.
