PM-1100
Precision Digital Modulator/Synthesizer
Product Brief

Seamless Pixel Joining
PULSE DATA MODES SUPPORTED
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.
4/8 bit
10/0 bit CTR*
10/0 bit LR**
• 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.
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.
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.
PM-1100 Electrical Specifications
• 1.8v core voltage, 3.3v I/O voltage, 5.0 volt tolerant I/O
• 100 MHz maximum video rate
• 80-pin Lowprofile Quad Flatpack (LQFP) Package
No External Components
Available Options
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.
