ANDOVER, Mass. -- Oak Technology Inc. here today announced a high-performance digital modulator that it said is the first all-digital laser modulator implemented entirely in CMOS.
Part of Oak's iRET family, the PM-1075 delivers very high-quality laser imaging while significantly easing system integration, the company said. The PM-1075 is designed for monochrome and color laser printers, digital copiers, copier/printers, and multifunction peripherals (MFP).
"Oak's Imaging Group developed the PM-1075 to revolutionize the laser modulator market," said Steve Alvarez, product marketing manager for iRET products. "By providing both industry-leading precision in the control of the laser spot size/position and unrivalled ease of integration, we intend to redefine the industry's reference system."
The PM-1075 features a 75-MHz video pixel rate. Independent control within a pixel gives the designer total control of the laser spot size and position to achieve high-quality text, line-art and photographic images.
Print controllers traditionally have used analog pulse-width-modulators (PWMs), which place restrictions on power supplies and have unique grounding requirements compared with digital modulators. However, Oak's all-digital CMOS design requires no external components or any special printed circuit board layout considerations, Alvarez said.
"The PM-1075 offers the inherent benefits of a digital modulator including reduced BOM, ease of integration and high-accuracy and linearity," he said.
The PM-1075's architecture enables controller designers to integrate the PM-1075, as they would traditional analog modulators, capitalizing on the PM-1075's 10-bit pulse width precision and high-speed 75-MHz video rate. Alternatively, the PM-1075 can be interfaced with a CPU, enabling functionalitits not offered with competing PWMs, Oak said.
The PM-1075 is sampling now, with production quantities to be available in the fourth quarter. Pricing for the PM-1075 is under $4.
