New Digital Media Processor: Conexant CX92755
Conexant announced a new single-chip media processor for multimedia display products such as digital signage, home automation/security and user interface control. The CX92755 is based on ARM™ Cortex-A8 processor and NEON™ single instruction, multiple data (SIMD) engine with Linux and Android development support.
The highly integrated SoC also includes an advanced HD video codec and graphics processor, integrated L1 and L2 cache, a PCI Express™ interface and DDR3 memory, The CX92755 integrates peripheral functions including a Class-D amplifier with speaker and line-out, a microphone input, back-light regulator, power supply controller and touchscreen controller.
The SoC also includes an embedded high-performance graphics processor, which supports display list processing, alpha blending, and color key control for advanced user interface operation and display effects. the CX92755 also support the major network connectivity standards such as Wi-Fi®, 3G, Bluetooth® and integrated Ethernet. The SoC also integrates Conexant’s HSSD/Smart DAA® (Direct Access Arrangement) interface, and an infrared device association (IrDA®) controller.
Additional features include Conexant’s advanced power management techniques, which support voltage scaling, clock gating, and dynamic power control functions for managed power applications.
The company did not provide further information such as the block diagram and product brief. However, it should be similar to their previous media processor CX92745 announced in December 2010 whose block diagram is shown below. The CX92755 has however a more advanced ARM Core (Cortex A8), HD video encoding capabilities and PCI express support but may lack the BT.656 video input port and USB ports.
The CX92755 will be available in sample quantities in Q2 2011, and volume production is expected on Q3 2011. The SoC is packaged in an 441-pin fine pitch BGA and priced at $9.50 each in volume quantities.
