The Microsemi SyncServer S650 M-Code Time and Frequency Instrument provide unprecedented synchronization flexibility and performance using Microchip FlexPort™ technology. The GPS M-Code referenced S650 is designed for high security, modern military electronics, and networks that require best-in-class synchronization performance easily adaptable to a wide range of applications.

Standard Management Access Security

All of the expected network management protocols are standard in the S650 M-Code. 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 the S650 CPU is bandwidth-limited for protection against DoS attacks. The local keypad on the server can be password-protected to prevent tampering.

Security-Hardening Option

The SyncServer S650 M-Code can be further hardened from both an NTP perspective and an authentication perspective through the Security Protocol License option that includes the security-hardened NTP Reflector. Operational hardening through the 360,000 NTP packet per second NTP Reflector with 100% hardware-based NTP packet processing also works with a CPU-protecting firewall by bandwidth limiting all non-NTP traffic. The Reflector also monitors packet flow for DoS detection and reporting, yet remains impervious to the level of network traffic as it operates at line speed.

Ultra-High-Performance NTP

The S650 M-Code can effortlessly support hundreds of thousands of network clients while maintaining microsecond-caliber NTP timestamp accuracy. NTP request throughput rates can exceed 10,000 requests/second while maintaining NTP timestamp accuracy. NTP monitoring, charting, and MRU logging assist in managing the NTP client activity. If the Security Protocol License option is enabled, the NTP Reflec- tor can process over 360,000 NTP requests per second with 20-nanosecond caliber time stamp accuracy with the added benefit of security-hardening the network port

IEEE 1588 PTP Input License

PTP input is useful for tunneling time to the S650 over the network. PTP input can be the primary time reference or used as a backup reference in the event of GPS signal loss. With GPS, the S650 can automatically calibrate and store observed network path delay asymmetries for PTP input use if the GPS signal is lost.

Dual DC Power Supplies

The dual-corded, dual-DC power supply option provides load sharing and an active power management system with hitless failover.

Antenna Accessories

Antenna cables and accessories enable versatile solutions to meet most installation requirements. Note: For complete information, see the SyncServer Options Datasheet (DS00002920).
