PM-1100
Precision Digital Modulator/Synthesizer
Product Brief
Descriptions (continued)
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
• Variable frequency sweep - the sweep mode generates a
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.
