Microsemi-SyncServer S650

sku Product SKU:  MIC-SyncServer S650

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 unprecedented and can even eliminate the need for additional signal distribution chasis and there is no degradation in the precise quality of the coherent output signals.

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 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.

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.

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 ReflectorTM. Anticipated future software enabled hardware options are GbE PTP operations and GLONASS support.

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.

Overview

Microsemi's 5125A makes accurate phase-noise measurements on signals from 1 MHz to 400 MHz, covering the full range of the most commonly used frequency references. The 5125A, which requires absolutely no configuration, displays measurement results seconds after the Start button is pressed.

Over 25 years of research at the National Institute of Standards and Technology (NIST) and in private industry have come to fruition in Microsemi''s phase noise test sets, which employ both direct sampling of the RF waveforms as well as cross correlation, making it possible to easily characterize the highest performance time and frequency references. The third generation, all-digital 5125A has been designed to meet the most demanding requirements. The 5125A can measure phase noise down to -145 dBc/Hz at 1 Hz offset from a 10 MHz carrier and -130 dBc/Hz at 1 Hz offset from a 100 MHz carrier, making it the perfect solution to characterize the very low noise frequency references, such as those used in RADAR and satellite communications.

The all-digital architecture employed in the 5125A uses advanced, high-speed, low-noise analog-to-digital converters in a patented architecture that does not require a phase-lock loop to make measurements. This provides multiple benefits for 5125A users:

  • Measurements are extremely easy to make, with no pre-calibration or configuration required.
  • Accurate results are presented within seconds of a measurement having been started.
  • Input carrier signals can be characterized much more accurately than before, to within 0.1 mHz of the carrier.
  • The stability or Allan deviation is measured in parallel with phase noise. The 5125A also includes a frequency counter with 13 digits of precision.
