Single Chip Processor For Multimedia Applications

Conexant Systems : 08 December, 2010  (New Product)
Conexant has released the CX92745 processor as a single chip solution with lower bill of materials cost for multimedia applications in interactive displays, kiosks and touchscreens
Conexant Systems has introduced the CX92745 processor for interactive display appliances (IDAs) with audio, high-performance video, and touchscreen functionality. IDAs are used as home Web terminals, interactive signage and kiosks, and in home automation and touchscreen-enabled multimedia applications. The highly integrated, single-chip solution allows manufacturers to simplify engineering design efforts and lower bill-of-material costs.

"We have made use of our strengths in mixed-signal and imaging processing to deliver a single-chip solution that enables very high-quality audio and video performance in multimedia display devices," said Sailesh Chittipeddi, Conexant president and chief operating officer. "Our new processor also has a feature-set that allows our customers to develop differentiated display appliances using a common silicon platform, which reduces engineering costs and product-development cycles."

The CX92745 display, media, and image processor includes Conexant's proprietary image processing pipeline, a high-performance HD video hardware engine, a graphics processing unit, and a powerful microprocessor to provide high-speed, high-quality photo rendering and multimedia processing. The new system-on-chip (SoC) solution also includes an integrated Class-D amplifier to maximize audio performance and power-efficiency, and an internal power supply controller to lower bill-of-material costs. The CX92745 also includes support for Wi-Fi, 3G cellular, Bluetooth, and Ethernet connectivity.

The new processor is based on an ARM RISC processor to support high-performance embedded applications design. The CX92745 also includes an integrated ARM vector floating point unit, large internal caches, and high-speed DDR2 memory to maximize multimedia and graphics processing capabilities. Additional features include a programmable LCD interface for analog and digital displays, and a touchscreen controller to enable low-cost, advanced capacitive touchscreen functionality. The processor also includes integrated USB 2.0 host and device ports, which enable high-speed, bi-directional data transfers and connections to USB peripherals. In addition, the processor integrates a BT.656-compatible video-in port to support camera and video peripheral interfaces.

In addition to high-performance system solutions for interactive display devices, Conexant's imaging portfolio includes highly integrated MFP SoCs for inkjet, laser, photo, and label printers. The company also offers fax SoCs and datapump solutions.

The CX92745 is sampling now, with volume production slated for January 2011. Evaluation kits and reference designs based on the new SoC solution will be provided to qualified customers at no cost. The processor is packaged in an environmentally friendly, RoHS/Green-compliant 400-pin fine-pitch ball grid array and priced at $9.00 each in production quantities.
