Time & Frequency Standard Network Time Server - SyncServer S650 (NTP / IRIG B)

GPS Referenced Time & Frequency Clock

The new SyncServer S650 Time and Frequency Instrument provides unprecedented synchronization flexibility and performance using Microsemi FlexPort technology. The GPS referenced S650 is designed for modern electronics systems and networks that require best-in-class synchronization performance easily adaptable to a wide range of applications.

Overview

The modular Microsemi S650 combines the best of time and frequency instrumentation with unique flexibility and powerful network/security-based features. The level of timing signal flexibility is powerful and can even eliminate the need for additional signal distribution chassis as there is no degradation in the precise quality of the coherent output signals.

  • GLONASS / BeiDou / SBAS option
  • PTP Grandmaster option
  • S650i model with no GNSS receiver installed
  • FlexPort timing technology efficiently and cost-effectively adds innovative "any signal, any connector" technology, eliminating the wasted space inherent with legacy style fixed-signal modules/BNCs
  • Multiple GbE network ports for easy network configuration and adaptation
  • Reliable and rugged design for long product life and wide application scope
  • Many security-hardened, network-based feature for stringent IA requirements

Unparalleled Flexibility

The base Timing I/O module with eight BNC connectors comes standard with the most popular timing I/O signals (IRIG B, 10 MHz, 1PPS and so on). When more flexibility is required, the unique Microsemi FlexPort Technology option enables six of the BNCs to output any supported signal (time codes, sine waves, programmable rates), all configurable in real time via the secure web interface. The incredible BNC-by-BNC configuration makes very efficient and cost-effective use of the 1U space available.

Timing and Design Reliability

The 72-channel GNSS receiver coupled with Microsemi's patented Active Thermal Compensation Technology provides excellent accuracy of <15ns RMS to UTC (USNO). Backstop this with a durable hardware design subjected to MIL STD 810G testing, high-reliability components extending the operating temperature range to a very wide -20DegC to 65DegC and a dual power supply option. Further, upgrading to a high performance oscillator, such as Rubidium atomic clock, keeps the S650 accurate for long periods in the event of a GNSS service disruption.

Ultra High Performance NTP

The S650 can effortlessly support hundreds of thousands of network clients while maintaining microsecond caliber NTP timestamp accuracy. NTP request throughput rates exceed 10,000 requests/second while maintaining NTP timestamp accuracy. If the Security License option is enables, the NTP Reflector can process over 360,000 NTP requests per second with 15ns caliber timestamp accuracy with the added benefit of security-hardening the NTP port. This can easily translate into sub-millisecond NTP client synchronization accuracy on a LAN.

IEEE 1588 PTP Grandmaster

Applications demanding very precise time accuracy can deploy IEEE-1588, the precise time protocol (PTP). The S650 PTP output license enables PTP grandmaster operations leveraging the built-in hardware time stamping on each LAN port of the S650. 

Multi-GNSS Constellation Support for enhanced Reliability

Timing integrity, satellite signal continuity, and timing reliability can be improved with the GNSS option that adds support for GLONASS, BeiDou, and SBAS constellations. With more satellites in view, timing performance can be improved in challenging environments, such as urban canyons. All SyncServer S650s ship with GNSS hardware ready to be enabled with a software license. The S650 is also available without GNSS in the S650i model.

Secure Networking

The four standard GbE ports accommodate more than 10,000 NTP requests per second using hardware time stamping and compensation. All network traffic to the S650 CPU is bandwidth-limited for protection against denial-of-service (DoS) attacks. For more secure NTP operations, enable the optional Security-Hardened NTP Reflector capable of 360,000 NTP requests per second all with 100% hardware-based NTP packet processing. The reflector is also a CPU-protecting firewall, bandwidth limiting non-NTP traffic to the CPU. It is also equipped with DoS detection, notification and protection against abnormally high NTP traffic.

Leverage Built-In Hardware

The SyncServer S650 includes additional built-in hardware features that are enabled through software license keys, such as the Security-Hardened NTP Reflector.

Standard Management Access Security

All of the expected network management protocols are standard in the S650. These include mandatory password access, HTTPS/SSL only (using the high encryption cipher suite), SSH, access control lists, service termination, SNMPv2/v3 and NTP MD5 authentication. All traffic to S650 is bandwidth-limited for protection against the DoS attacks.

Intuitive, Secure and Easy to Use Web Interface

The modern web interface is the primary control interface for the S650. Once the keypad and display are used to bring the unit online, complete status and functions are easily found via the well-organized left side expanding/collapsing navigation menu. At-a-glance dashboard presentation combined with logical organization and intuitive controls make configuring the S650 quite easy.
