PM-2060i
Precision Digital Modulator

• 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.
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:
• 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.

• 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.
