  • 2.048 Mbit/s, 2.048 MHz and 1.544 Mbit/s synchronization clock signal for legacy equipments
  • Multicast & Unicast operation ideal for use in Telecoms environment


The Precision Time Protocol (PTP) is a solution for the distribution of synchronization over IP-based packet networks such as IP, IP/MPLS, Ethernet, IP/xPON and IP/xDSL networks. PTP is also known by the name of the corresponding standard IEEE 1588-2008.

Brandywine offers a comprehensive range of PTP products covering all synchronization needs in the telecommunication domain. The OSA 5320 PTP Slave is designed to interoperate with PTP grandmaster clocks from Oscilloquartz or from other vendors. The OSA 5320 consists of a PTP protocol engine which connects to one or several distant PTP Grandmaster clocks over an IP or Ethernet network.

The PTP Slave delivers frequency, phase and time-of-day over a set of output ports featuring a variety of output formats. The output port section is divided into a set of standard output ports and a pluggable Output Extension Module. The OSA 5320 is fully manageable. So-called PTP Profiles are used to configure those parameters which are crucial for the interoperability with the connected grandmaster clock.

Typical applications are the synchronization of 2G, 3G, cdma2000 and WiMax basestations, of xPON optical line terminals, etc. PTP allows the distribution of accurate frequency, phase and time-of-day to these applications even in cases where the transport network is asynchronous. The typical PTP architecture consists of a PTP grandmaster clock which delivers synchronization to a number of PTP slave clocks.
