Synchronization is key in many applications
Radio access
networks
Highly accurate phase and frequency
synchronization for efficient use of spectrum
Migration from NTP- to PTP-based timing for
increased timestamping accuracy
Financial trading
Digital cable networks
Timing distribution to remote PHY devices in
digital infrastructure deployments
Higher accuracy and uncompromised
reliability for mission critical applications Power utilities
Data center
infrastructure
Common and precise time basis for
synchronization of distributed data bases
Keeping cameras, mixers, recorders and
monitors tightly synchronized

SDI is a synchronous, broadcast-
specific transport technology
SDI monolithically integrates
video signals, framing and timing
into hardware, creating
complexity and inflexibility
challenges with synchronizing
audio and video
Evolve towards IP network with
flexible processing of video and
audio and ancillary data
Towards standard IP transport of video, audio, ancillary data as well as time

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)

GNSS outages need to be mitigated with
network-based synchronization delivery
IEEE 1588 necessary for IEC 61850 substation
automation and IEEE C37.118 synchrophasor
PTP profiles:
IEC/IEEE 61850-9-3
IEEE C37.238-2011
IEEE C37.238-2017
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
Challenges
Increasing accuracy GNSS vulnerability
Lack of visibility Standardization

IRIG and PPS provide time

GNSS as highly accurate local
time reference
Network Time Protocol (NTP)
