CX92235
Conexant’s portfolio includes a comprehensive suite of semiconductor
solutions for communications and consumer applications.
A complete controller solution for laser and inkjet photo
printers and MFPs
Conexant’s product line of highly integrated imaging solutions and
system-on-chips (SoCs) is one of the most complete in the industry. The
CX92235 (DC2350) is a comprehensive controller solution for color and
monochrome laser and inkjet multi-function printers (MFPs) and digital
photo printers. The device integrates many advanced technical features
that improve the pixel processing speed as well as the output image
quality. The modular design of the firmware allows manufacturers to
develop multiple products with a single imaging SoC, which reduces
engineering development and bill-of-material (BOM) costs.
The CX92235 features very high-speed hardware image processing
accelerators, system I/O and a powerful ARM 926EJ-S core with a
memory management unit and a vector floating point processor to
deliver the power required for high-speed imaging applications. The highperformance imaging processor along with additional imaging hardware
blocks enables fast raster image processing (RIP) for page description
languages (PDLs), which improves complex text and graphics laserprinting speeds. The CX92335 has market-leading color copying speeds
of up to 30 pages per minute.
Other key features include support for tandem color laser printers and a
dual-image-pipeline architecture that automatically segments texts from
photos, and optimally processes the images without degrading system
performance. A complete hardware and software development kit is
offered to simplify product-development efforts and allows designers to
deliver product to market more quickly.
The CX92235 integrates many advanced features such as an Ethernet
MAC, a memory card controller, a LCD controller, and contains an
enhanced image processing pipeline that improves the pixel processing
speed as well as the output image quality. Two USB 2.0 high-speed
ports and a peripheral bus support connections to cameras, memory
cards and USB peripherals, including Bluetooth® and WiFi® 802.11 b/g/n
devices, and V.34 fax modems.
