Network Time Server - SyncServer S650 (NTP)
Accurate, Secure and Flexible Time and Frequency Standard
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.
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 configurations 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 best-in-class time accuracy of <15ns RMS to UTC. Backstop this with a durable hardware design subjected to severe shock and vibration testing, and high reliability components that extend the operating temperature range to a very wide -20DegC to 65DegC. Further choose the dual power supply option with SNMP trap enabled monitoring to avoid time service interruptions. As with all Microsemi time servers, upgrading to a high performance oscillator such as a Rubidium atomic clock, keeps the S650 accurate for a long time in the event of a GNSS service disruption.
Unbeatable holdover performance

The standard S650 is equipped with a crystal oscillator that keeps the S650 accurate to nanoseconds when tracking GNSS. However, if GNSS connectivity is lost, thereby placing the server in holdover, the oscillator will begin to drift impacting timing accuracy.
Upgrading the oscillator improves the holdover accuracy significantly.

For example, consider the drift rates below for the standard oscillator compared to the OCXO and Rubidium upgrades: Oscillator Holdover Drift, (1st 24 hours),  Standard 400 microseconds, OCXO 25 microseconds, Rubidium <1 microsecond
Cutting-Edge Active Thermal Technology
Multiple temperature sensors and cooling module allow for different control strategies based on installed oscillator type.

Stabilization of the temperature inside the chassis allow for unbeatable holdover performance with the different oscillators.

Full monitoring and status alarms for the thermal compensation status.
Unprecedented NTP Accuracy
The Stratum 1 level S650 derives nanosecond accurate time directly from the atomic clocks aboard the GNSS satellites.

By using an integrated, 72-channel GNSS receiver, every visible satellite can be tracked and used to maintain accurate and reliable time.

Even in urban canyon environments where direct satellite visibility can be limited, manually inputting the position can be sufficient to acquire accurate time even from a single intermittent satellite.
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 ReflectorTM with line speed, 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 network traffic.
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.
Introducing the first HW NTP Firewall:

Implementing all NTP operations in hardware (FPGA), the NTP Reflector option turns the time server to be virtually hacker-proof.

All non-NTP and non-allowed packets are dropped while maintaining ultra-high capacity of more than 120,000 NTP requests per second providing for the best possible time stamp accuracy.
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.
