Driving the Digital Lifestyle

Seamless Pixel Joining

Because of the PM-1100's all-digital design and unique digital

addressing of transition edges, pixel joining is totally seamless. There is no "recovery" time or "dead zone" between pixels Frequency Sweep

The PM-1100 frequency synthesizer has two modes: fixed frequency generation and variable frequency sweep.

? Fixed frequency generation - the fixed mode generates a single fixed pixel width (frequency) throughout the scan line.

? Variable frequency sweep - the sweep mode generates a

frequency modulated output using a preprogrammed modulation function in the Frequency Sweep LUT (FS LUT) resulting in the generation of a variable frequency as the laser sweeps across the page.

All-Digital Design

The PM-1100 Precision Modulator technology is a proven 3rd

generation design implemented in standard CMOS technology. With its unique design, the modulator uses a single reference clock,eliminating the need for high-speed or multiple clock frequencies.No External Components

The PM-1100 features an all-digital modulator, requiring no external components such as delay lines, beam detect synchronization logic,external SRAM, etc. The output of the modulator directly feeds the laser diode driver.

No Modulator Chip Calibration

Due to its all-digital design, the PM-1100 is inherently linear; no

alignment or calibration of the modulator chip is necessary, as is the case with many analog modulators. The PM-1100 operates at full specification without any tuning of components.PM-1100 Electrical Specifications
