Overview

NetTimeLogic’s RTC Master Clock is a full hardware (FPGA) only implementation of a synchronization core allowing to read and write a I2C Realtime Clock (RTC) like the DS1307 or MCP7941x. Access to the RTC is done from the FPGA without software interaction. It allows storing and recovering time from a non-volatile storage. Reading and Writing is aligned with the Square Wave Output of the RTC. On a read, a nanosecond part is calculated to achieve maximum accuracy. Conversion from/to 32bit second, 32bit nanosecond time format from/to the date format used by the RTC is completely done in HW. This allows running RTC synchronization completely independent and standalone from the user application. The core can be configured either by signals or by an AXI4Light-Slave Register interface.

All calculations and corrections are implemented completely in HW.

Key features

  • Real Time Clock (RTC) Master Clock
  • Supports DS1307 and MCP7941x (and compatible) Real Time Clocks (RTC) and self-configuration at startup
  • Allows to synchronize the internal clock to the RTC and vise versa
  • Built-in I2C controller with configurable baud rate
  • Aligned writing and reading of time with the RTC PPS
  • Hardware time conversion from Time of Day format (hh:mm:ss dd:mm:yyyy) into seconds since midnight 1.1.1970 (Linux, TAI, PTP)
  • PI Servo Loop in hardware
  • In combination with a Adjustable Counter Clock from NetTimeLogic: synchronization accuracy: +/- 100ns
  • AXI4 Light register set or static configuration

HQ: Switzerland
NetTimeLogic offers full time synchronization, network redundancy, and time sensitive networking solutions as vendor independent FPGA IP cores and design services in these fields. We provide full hardware implementations of synchronization IP cores such as PTP-Transparent-, Ordinary-, Grandmaster- or Hybrid-Clocks as well as IRIG-, PPS-, NMEA-Masters and Slaves, a NTP Server and Client and a RTC-Master and a DCF-Slave. For network redundancy we provide a full hardware implementation of the HSR and PRP protocols and for time sensitive networking we provide also a full hardware implementation of TSN suporting all major standards. All IP cores can be combined to a complete synchronization or network redundancy solution which can act e.g. as bridge between the different times synchronization protocols or as a network redundancy solution with time synchronization support. We also offer design services in the field of FPGA and Embedded Software development. With our 20+ years of experience and certification in FPGA and software development as well as product and project management we bring in our expertise to design the best possible solution for you. We understand your needs and can give you support to develop a best in class product. We offer swiss quality engineering - highest quality, always on time!
