Overview of Laser Control Cores
Development of on-chip high-precision analog cores
Having the qualities of both high performance and low power consumption, system-on-chip (SoC) on-chip pulse width modulation (PWM) cores for controlling lasers are providing solutions for printers and copiers which use lasers beams in their printing processes, as these devices are being developed to meet demands in both business and personal sectors for high-quality images.
PWM circuit performance (namely, operation speed and precision) has a reputation for generally deteriorating when the circuits are placed on-chip. We at NEC Electronics have nevertheless successfully developed our own original high-speed, high-precision technology which has led to the creation of SoCs containing PWMs which do not suffer from performance deterioration even when the PWMs are placed on-chip.
Moreover, by narrowing down the fields to which the cores will be applied, to printers and copiers, we have limited the functions to those which will sufficiently meet the demands for these devices, while improving usability and controlling core size.
Orders for this PWM laser control core are now being accepted, beginning with the CB-12 (150 nm nodes) version. A fine-process series, the CB-90 (with 90 nm nodes) and later versions, is also being rolled out.
A dedicated evaluation board and test chips for the PWM laser control core are also available for use with software development and reducing risks associated with designing circuits to be placed on-chip.
Features of PWM laser control cores are as follow.
- Basic functions optimized for printers and copiers
Resolution: 8 bits, pulse rate: 100 MHz min. - Placed on-chip, yet without function degradation
Heretofore unavoidable degradation of PWM core functions resulting from on-chip placement of circuits has been overcome with newly developed high-speed, high-precision circuit technology. - High integration, high-speed operation, low power consumption, and high noise resistance
- Macro size and power consumption reduced by limiting functions to limited presumed applications
- A high-speed operation, highly noise resistant chip could be achieved with this chip, which eliminates the need for external wiring on the package and by placing the oscillator on-chip.
- Development environment geared to placing circuits on-chip is available.
- Chips supplied for testing PWM laser control cores
- Dedicated evaluation board available for testing chips
- Developed sequentially for use with design boards for SoCs of every process generation

Examples of using laser control cores
Evaluation board for laser control cores
When connected to a USB port via a PC, this system permits ready evaluations just by connecting to a printer engine and is useful for checking printing data and system development.
