Our compact Oscilloquartz PTP timing technology now complies with the latest PTP profiles for time, frequency and phase synchronization in both power utility and broadcast networks. By extending the capabilities of our pluggable OSA 5401, the market’s smallest PTP grandmaster clock, and the highly versatile OSA 5405, we’re enabling utility and broadcast networks to achieve sub-microsecond synchronization. Now electricity companies can harness the accuracy needed for smart power grids, and media enterprises can meet key timing challenges.

Step 1: Synchronizing broadcasting devices Step 2: Backup with network-based delivery
Combining GNSS-based and network-based timing for best performance
Seamlessly introducing PTP in broadcasting networks
• Installing very compact grandmasters
• Satellite-based timing at any site
• Backed up by network-based PTP
• Use SMPTE ST 2059-2 /AES67 PTP profiles
• Central, redundant high-performance
grandmasters
• Sync-aware network devices (TC, BC)
• Potential use of telecom profiles (G.8275.1/2)

As synchronization is mission-critical, real-time
information about sync quality is vital
Moving from 1ms to 1µs time accuracy requires
NTP to be replaced by PTP
