The new M50 form factor for the Qulsar processor with a Precise Time Protocol (PTP) system on-chip dramatically reduces the cost, power budget and board space for packet based time and frequency synchronization. The module embeds a platform including real-time operating system, flash file system, communication stacks and more. A validated IEEE1588 - 2008 compliant protocol stack is integrated. An advanced loop control manages complex network topologies and loads.
The M50-34 is an optimized design based on the C34 controller fromQulsar . Designers can fit the miniature sub-system containing a complete IEEE 1588-2008 ordinary clock implementation on less than a 30x30 mm board space.
For a slave side application the M50-34 replaces the PHY and adds functionality to replace a local oscillator by providing packet based timing. As Grandmaster it converts high quality clock input information to the packet network as a master clock.
The M50-34 shortens time to market for products requiring IEEE 1588-2008 functionality; it reduces the cost of synchronization while replacing the PHY including peripheral components, but also the local oscillator and the real-time clock. The M50 can be integrated without the need for host programming. If you want to save costs even more, but there is application space on the module to relocate the complete host functionality to the module.

The M50-34 requires no on-module programming if inserted as a subsystem to an existing processor. The existing processor can communicate by implementing a set of HMI like commands. A generic use of precise time can then be made by use of the signal presentation on the PPS, ToD and reference frequency port pins on the module.
When inserted in the Ethernet transmission chain, the M50-34 can leverage the components ability to manage the Precise Time Protocol, sharing the same IP address as the local network processor up to 60 Mbit/s. This is done while running the time and synchronization stack for IEEE 1588 up to the standards maximum sync rate 128 per second.
More advanced users can chose the C-programming environment of the Developer IDE software. A top level system API enables programmers to add applications alongside the application for the disciplined clock and make use of the precise time. Even more advanced programmers can add functionality to replace the original local processor. Besides the PTP engine several other API’s, like the POSIX RTOS are available for system programming.
*) In-system power consumption when running 128 sync messages and 64 delay requests per second. The processor uses less than 10% of this and requires no extra cooling.
