High Performance Pulse Train Output (PTO) with PRU-ICSS for Industrial Applications Reference Design


Design files


The TIDEP0027 High Performance Pulse Train Output (PTO) with PRU-ICSS for Industrial Application combines the AM335x Sitara processor family from Texas Instruments (TI) and the PTO module into a single system-on-chip (SoC) solution. The design is based on the TMDSICE3359 Industrial Communications Engine (ICE) but can be also used with other PRU-ICSS capable development boards.

  • High speed/frequency with high precision for accurate PTO control and synchronization
  • Implementation without external ASIC or FPGA
  • Implementation on PRU-ICSS with Sitara processor
  • Contains PRU-ICSS firmware in source code and can get adoptable by customer
  • Easy evaluation with TMDSICE3359 Industrial Communication Engine (ICE) EVM
