PM-2060I

PM-2060i Precision Digital Modulator Imaging Software Driving Driving the Digital Lifestyle Processors Quatro SOCs Solutions Product Brief Zoran Corporation 1390 Kifer Road Sunnyvale, CA 94086-5305 www.zoran.com The PM-2060i Precision Digital Modulator delivers the highest quality resolution enhancement available today. The PM-2060i is a single-chip solution that addresses all image enhancement functionality for virtually any resolution laser printer, multifunction peripheral (MFP), laser fax, or digital laser copier. The PM-2060i supports engine speeds up to 60 pages per minute at 600 dpi independent of page description language, CPU, compression scheme, or host application. The result is a complete enhancement solution that maximizes performance, while minimizing development time, cost and complexity. Benefits • Complete, single-chip laser resolution enhancement solutions reduces overall cost and time-to-market • Best edge enhancement available • High-resolution rendering • Multi-bit color and grayscale rendering for photo-realistic output • Full support for monochrome and four-color printing Key Features • Text and line-art edge enhancement • 2x high-resolution rendering (vertical and horizontal) • Multi-bit (contone) input mode • Contone Auto Position mode • Economy mode reduces toner used while preserving print quality • Full support for four-color printing • Two source data input modes (serial video, parallel video) • On-chip precision digital modulator (66 MHz max/3 MHz min video rate) • Multiple print engine resolution support - 300 to 800 dpi • Internal beam detection synchronization • Internal line store memory • Internal print engine calibration table • Supports 13.65" maximum scan line length at 600 dpi Description High Integration The PM-2060i is a completely integrated resolution enhancement solution for color and monochrome laser printing devices. It combines all the circuitry required to implement text and line-art edge enhancement, high-resolution rendering, and multi-bit color and grayscale rendering. The PM-2060i has serial and parallel data interfaces, internal line store memory, internal precision digital modulator, internal LUT memory, and clock scaling circuitry. It requires no external memory, delay lines, or phase-locked loops (PLLs). Superior Enhancement Based on Zoran's proprietary image enhancement technology, the PM-2060i offers a range of advanced image enhancement modes: High-resolution Rendering, Edge Enhancement, Multi-bit Color and Grayscale Rendering, and Contone Auto Position. High-Resolution Rendering This mode accepts 2x source data, rendering 1200 dpi text, line-art and images on 600 dpi engines. The PM-2060i prints the 1200 dpi input data using precision digital modulation, doubling both the horizontal and vertical resolution of a 600 dpi engine. Edge Enhancement This eliminates "jaggies" to improve the appearance of text and lineart. The PM-2060i uses the industry's largest analysis window to generate the dot size and position information for the internal modulator, which has sub-nanosecond precision. The result is an effective doubling of the resolution of text and line-art. For MFP and low-end applications, the edge enhancement feature can also scale source data at 1/3 and 1/2 resolution of the print engine, while enhancing output. Multi-bit Color and Grayscale Rendering The multi-bit modes accept up to 8-bit-per-pixel input data (600x600x8, 600x600x4, etc.) to produce 256 shades per color plane for true photo-realistic output. The PM-2060i screens image data or accepts pre-screened image data and outputs to the print engine using the internal digital precision modulator. The multi-bit modes are ideal for printing scanned images or for printing from contone-capable PDLs. 01/06-MMCP Imaging-PM-2060i-PB-1.2 PM-2060i Precision Digital Modulator Driving Driving the Digital Lifestyle Product Brief Descriptions (continued) Contone Auto Position This mode enhances 600x8 and 600x4 data by detecting solid black and white areas, and automatically positioning gray dots, or varying width pulses, adjacent to solid blacks to improve anti-aliased text, line art and halftone dots. Versatile Implementation Beyond the elimination of external components, the PM-2060i has been designed for easy implementation on any controller design. It offers significant advantages over competing designs: • While other solutions require a 4x or 8x video clock, the PM-2060i only requires a 1x video clock from the print engine. This eliminates problems associated with transmitting very high frequency 4x or 8x clocks around on the controller board. • Unlike solutions requiring external circuitry to synchronize with the beam detect (BD) signal, the PM-2060i has internal, automatic BD synchronization to within 1/256nd of a dot clock. • The PM-2060i has sub-nanosecond positioning accuracy (resolution) for total control of laser pulse width and position within a video clock period. • Unlike analog modulators that require linearization and inherently possess dead zones, the PM-2060i has an all-digital modulator. It is inherently linear, has no dead zones, and delivers a significant increase in subpixel placement accuracy, for exceptionally fine detail. • Internal LUTs are used to store the print engine calibration tables that provide the correction necessary to compensate for print engine, toner, paper, and environmental variables in the printing process. The LUT is addressed and downloaded directly by the CPU at power up or between pages. Different LUTs may be loaded between color planes for maximum flexibility. • The PM-2060i is designed for maximum flexibility to preserve your investment, offering full programmability of all functions. This enables adding new features as products grow and mature. Designs based on the PM-2060i can easily adapt to changes in CPUs, speeds, resolution, page description languages, and host applications.
