Digital Timing Platform™

Programmable System-on-Chip (SoC)

Solutions in Biomedical, Instrumentation and Precision Control Applications

Highlights

Our Digital Timing Platform™ is a family of synchronous counters optimized for custom design. It supports complex, programmable, digital pulse generator functions. It also provides automatic timing for biphasic and alternate pulses for electrical stimulation and other applications. Its flexible design allows for unlimited, reconfigurable signal solutions with the number of synchron• Pulse Generatorsous outputs defined by specific application. The Digital Timing Platform™ can be used for implementation of various families of the off-the-shelf digital pulse generator components or as a part of the larger SoC device.One example of the digital pulse generator family is the EH2000™ Series - patent pending. Those prototypes were developed for low frequency electrical stimulation applications and utilized in research projects. High frequency or lower supply voltage applications are possible with an appropriate choice of the FPGA or SoC technology.
