DK5 Development Kit

Applications

• IEEE 1588-2008 Grandmaster or Ordinary Clock with three different oscillator alternatives: IC internal, TCXO, OCXO
• Grandmaster operation with PPS and ToD input from GPS or other Time Source
• PPS, ToD and syntonized frequency output
• Compact OEM design.

Introduction

The DK5 is a complete kit for the development environment of Conemtech connected embedded controllers where IEEE 1588 is used for time synchronization. The kit is intended for the development of compact Grandmasters, high precision slaves or general ordinary clocks in the IEEE1588 network. It is based on the C34 microcontroller located on an M50-34 subsystem-module. 

The functionality of the system is delivered by the C34 controller which is a dedicated controller for time synchronized applications. Its outstanding features stem from the ability to analyze and act on gate level, in real-time. The system has the ability to sustain processing of almost 20 Mbit/s of IP dataflow, while running the IEEE 1588 Protocol software in the background. The M50-34 module embeds a complete software platform including real-time operating system, flash file system, TCP/IP communication stack, FTP and telnet server. For the execution of the IEEE1588-2008 protocol, a software stack with fully compliant Ordinary Clock implementation is integrated. The development environment enables the application designer to manage projects with configurations for different clock modes and precisions.

Features

• Two Ethernet 10/100 RJ-45 connectors with auto sensing PHYs
• Second Ethernet also available on MII/RMII connector
• Three asynchronous serial ports
• Three internal oscillator alternatives, one external input
• PPS and ToD input from GPS or other time source, for Grandmaster mode
• PPS and ToD inputs and outputs plus a syntonized frequency output
• Time and Frequency signals available on five SMA coaxial connectors.

Programming and Debugging

The Developer IDE comes set with a framework of programming tools and the chosen form factor profile for time synchronization applications. A source code debugging feature and an event analyzer assist the programmer throughout the project. The "ready-to-go" software includes the IEEE 1588-2008 protocol software stack with an Grandmaster API for the type of Ordinary Clock variant. For slave application programmers an advanced Loop Control filter and Best Master Clock (BMC) algorithm for the slave application. A special Jitter analysis monitor software for the PC is also included in the kit

Block Diagram

The Development Kit is designed for an optimized IEEE 1588 communication application and the Grandmaster mode. The kit comes set with an on board TCXO oscillator, but can be adapted for different oscillators: on-module, on-board, external. The kit has an optional input for an external reference (eg. GPS).

A host system interfaces to the board via the SPI port and a separate debug port connects to the development system via the trace adapter
