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.

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.

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.
• 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.
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:
• 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.
• 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.
Range of Configurations
The PM-2060i is available in a range of configurations to
meet a variety of design, performance and cost requirements.
The PM-2060i family includes the following:
• 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.
PM-2060i PM-2040i PM-2020i PM-2010i
• 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.
