Cirrus Logic Inc. released its CRD92688-RX reference design, a feature-packed, cost-effective digital home theater recorder chipset platform that merges the company's Class D-based digital amplifier IC together with its reference platform of ICs and software for DVD recorder products, including the CS92688 MPEG-2 encoder, the CS98300 DVD processor, the CS44600 digital amplifier and the CS4344, CS8416 and CS5340 audio converter ICs.

According to Cirrus Logic, this reference design is unique because all digital audio and video processing is performed by the CS98300 coupled with an on-board DSP engine. This combination is powerful enough to eliminate a separate dedicated DSP required by some competing chipset platforms, the press release said.

"The CRD92688-RX home theater recorder reference design showcases Cirrus Logic's unique breadth of expertise in digital entertainment through its audio and video digital signal processing and analog and mixed-signal converter ICs," shared Jack Guedj, VP of Video Products Marketing at Cirrus Logic. "Advanced and proprietary algorithms have now been posted onto Cirrus Logic's standard DVD recorder reference designs to create this complete home theater recorder hardware/software reference platform."

The company expects its platform to be manufactured and marketed to consumers as a single product, packaged and sold with home theater-style speakers for multi-channel surround sound, with retail prices raging from $199 to $249, depending upon level of features.

The robust reference design also includes progressive scan playback, composite S-Video and digital video input, a front-panel headphone jack and support for the NTSC, PAL and SECAM broadcast formats. A complete manufacturer's tool kit is also available that features hardware, software, BoMs, schematics, Gerber files and documentation.
