MICROCHIP TIMING & SYNCHRONIZATION

TimeProvider 4100 Release 2.2

Precise Timing Grandmaster with Gateway Clock, PRTC-B, High-Performance Boundary & Enhanced PRTC

TimeProvider® 4100 is a family of solutions based on a hardware platform with a choice of oscillators that can be complemented by optional expansion modules and by unique differentiating software options that are made available in successive releases. This approach ensures the preservation of investments in a platform that evolves with industry needs and standard evolutions.

 

New Features for Release 2.2

TimeProvider 4100 Release 2.2 builds upon prior releases by adding the following key capabilities.

  • Redundancy : one Active unit and one Standby unit are directly linked to offer a redundant solution enabled via software, no need for additional hardware module
  • Multiband GNSS : new receiver module inside the unit is now capable of supporting single band by default and can be enabled via license to support Multiband for mitigation against ionospheric delays, no need for additional hardware module
  • Super OCXO : additional oscillator choice with enhanced timekeeping holdover performance
  • Security : enhanced capabilities including support for standard authentication servers (TACACS+, Radius), enhanced SSH with support for high security profiles as well as enhanced anti-jamming & spoofing capabilities and metrics
  • Monitoring : added support for legacy signals monitoring (E1/T1, 10Mhz) with MTIE

Flexible Architecture

  • Rich base platform with support for PTP, NTP and legacy frequency timing interfaces
  • Ports of many types : 4xE1/T1, 2xRJ45 1GE, 6xSFP 1GE, 2x1pps/ToD, 1 GNSS, 1 Craft

  • Telecom 2008, Default profile, G.8265.1, G.8275.1, G.8275.2
  • SyncE input & output
  • NTP with MD5 security
  • Multiple packet services per unit, each port can be configured separately for master or client or probe or NTP
  • Dedicated management port (RJ45 or SFP)
  • Operator can select number and types of ports and interfaces that are necessary to deploy and scale for use cases such as 5G, cRAN, oRAN, DOCSIS remote/MAC PHY, etc.
  • Primary Reference Time Clock : Class A (100ns), Class B (ITU-T G.8272, 40ns), ePRTC (30ns)
  • 790 PTP clients capacity at full rate of 128 packet per second in unicast
  • Sub-tenancy model enable to double capacity and scalability by using a master unit connected to downstream client units; port count is doubled with two units.

Resiliency & Redundancy

  • Dual power input for power redundancy
  • Fan less device minimizes risks associated with rotation and moving parts
  • Heat sinks and heat pipes enable great scalability with SFP and SFP+ ports
  • Oscillator options (mini OCXO, OCXO, super OCXO, Rubidium) for time-keeping and holdover enhanced performances depending on use case and requirements (edge, aggregation, core)
  • Support for all major GNSS Constellations (GPS, GLONASS, Beidou, Galileo) and SBAS allows for enhanced resiliency by enabling to lock to more satellites
  • Support for Multi-band GNSS to mitigate time delay due to solar storms and ionosphere effects. Each unit is hardware enabled with Multiband receiver. L1 is set per default, upgrade to multiband does not require a new hardware module
  • Microchips' patented active thermal compensation technology for excellent accuracy of <10ns RMS to UTC (USNO)
  • PTP client input with patented automatic asymmetry compensation (AAC) provides best of class assisted partial timing support (APTS) on 32 paths as back up to GNSS signal. AAC with APTS mitigates for packet delay variation (PDV), jitter and asymmetry
  • Geographical network redundancy for failure leverages IEEE 1588 PTP Best Master Class Algorithm (BMCA)
  • Software redundancy with no need for additional hardware modules. Two units use Active/StandBy model with direct fiber link, co-location, continuous health monitoring and fast switching from passive to active when needed
  • TimeProvider 4100 is a key member of the virtual PRTC solution. TP4100 can be configured as ePRTC, Gateway Clock as well as with High Performance Boundary Clock. vPRTC provides an architecture for redundant, resilient and highly accurate distribution of phase (PRTC-A over long distances) using optical networks such as DWDM

  • TimePictra can present monitoring results as well as graphs for ePRTC and chains of high performance boundary clocks

Multiple Operation Mode

Mode of Operation is an essential capability focused around which of the multiple inputs can be used as synchronization reference. The unit can still behave as a fully functional grandmaster from an outputs standpoint and also has the capability to monitor various kinds of inputs, but a key set of specific inputs can be used as reference for a specific Operation Mode. Various Operation Modes will be introduced over time on TimeProvider 4100. TimeProvider 4100 now supports three Operation Modes:

  • Gateway Clock mode
  • High-Performance Boundary Clock mode (Single domain and Multi domain)
  • Enhanced Primary Reference Time Clock (ePRTC)

Gateway Clock Mode

  • New class of synchronization device with multiple inputs and fan out capabilities for distribution of timing flows to multiple end points
