SyncServer S650 SAASM
Overview
The SyncServer S650 SAASM model will be discontinued on December 31, 2021. See the Product Discontinuance Notice found at https://my.microsemi.com. The replacement is the SyncServer S650 M-Code.GPS SAASM Referenced Time & Frequency Standard
The SyncServer S650 SAASM Time and Frequency Instrument provides unprecedented synchronization flexibility and performance using Microsemi FlexPort™ technology. The GPS SAASM 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.
Unparalleled Flexibility

The modular Microsemi S650 SAASM combines the best of time and frequency instrumentation
with unique flexibility and powerful
network/security-based features.
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 FlexPortTM Technology option enables six of the BNCs to output any supported signals (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. Similar functionality is also applied to the two input BNCs. Unlike legacy modules with fixed count BNCs outputting fixed signal types per module, FlexPort technology can allow up to 12 BNCs output in any combination of supported signal types.
This 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.
Superior Low Phase Noise Performance
For applications requiring superior low phase noise (LPN) 10 MHz signals, two different LPN modules are available. Each module has eight extremely isolated 10 MHz LPN outputs with each module offering excellent levels of LPN or Ultra LPN performance.
Robust Timing and Design
The GPS SAASM GB-GRAM MPE-S Type II PPS receiver coupled with Microsemi's patented active thermal compensation technology provides excellent accuracy of <20 ns RMS to UTC (UNSO). This is all in addition to a durable hardware design subjected to MIL-STD-810G testing, high-reliability components extending the operating temperature range from -20°C to 65°C, and a dual power supply option. In addition, upgrading to a high-performance oscillator, such as a Rubidium atomic clock, keeps the S650 accurate for long periods in the event of a GPS service disruption.
Secure Networking
Security is an inherent part of the S650 SAASM. In addition to many security features and protocols, unsecure access protocols are deliberately omitted while remaining services can be disabled.
The four standard GbE ports, and two optional 10 GbE ports, accommodate more than 10,000 NTP requests per second using hardware time stamping and compensation. For more secure NTP operations, enable the optional security-hardened NTP Reflector with line speed, 100% hardware-based NTP packet processing.
DISA/DoDIN Approved Product
DISA Joint Interoperability Test Command (JITC) has tested and certified the SyncServer S650 SAASM Network Time Server for Cybersecurity/Interoperability compliance, and listed it on the Department of Defense Information Network (DoDIN) Approved Products List (APL). The SyncServer S650 SAASM meets the critical Unified Capabilities Requirements as a Timing and Synchronization device and is certified for joint military use.
Leverage built-in hardware
The S650 SAASM includes additional built-in hardware features enabled through software license keys such as the security-hardened NTP Reflector and IEEE 1588 PTP output/input operations.
The SyncServer S650 SAASM - the best choice for mission-critical operations.
