Interactive Multimedia Displays Getting Single-Chip Solution from Conexant

Since the popularity of interactive multimedia displays in various field has constantly increased over the past few years, Conexant has developed and now launched the CX92745 processor that targets displays delivering audio, high-performance video, and touchscreen functionality and enabled a major simplification in design and bill of materials.

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.

Additionally, 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.

Moreover, the CX92745 also includes support for Wi-Fi, 3G cellular, Bluetooth, and Ethernet connectivity.

According to Conexant, their new processor is based on an ARM RISC processor to support high-performance embedded applications design and 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.

Plus, 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, while also integrating a BT.656-compatible video-in port to support camera and video peripheral interfaces.

“We leveraged 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,” concluded Conexant's CFO.

The CX92745 is sampling now, with volume production slated for January 2011 and has been priced at $9.00 each in production quantities.
