Network Time Servers FAQ

1. What is a Network Time Server?

The general descriptive term 'network time server' can apply to any instance of the Network Time Protocol (NTP) server software running on a computer/server platform. The product term, 'Network Time Server' generally applies to a rack mounted network appliance that acquires time from an external source, maintains time in its internal local clock, and supplies time to a connected network using the network time protocol NTP.

2. Why should I synchronize my network?

Many operational processes (business and IT related) that occur within the network depend on accurate network timing. Further, more and more applications that support eBusiness and other enterprises are dependent on conducting their functions over the Internet. 

3. What's important in selecting a Network Time Server?

As in selecting any product or service there can be a long list of attractive features and Microsemi network time servers are no different. However, the list usually can be reduced to a few critical features that make a world of difference in installing and using the server, as well as some that may seem important but are not.

4. Which Server is for me? SyncServer S600 or the SyncServer S650?

GenTek representatives will almost always recommend the S650 over the S600 for several reasons:

      a.  The S600 and the S650 chassis cost the exact same thing.

      b.  The S650 has two expansion slots.  The S600 has none.

      c.  The S650 has significantly more capability and functionality because of the two slots.

      d.  As new modules are released, it's likely it can be added to your S650.  Since the S600 has no expansion capability, it cannot use the modules.

      e.  Since the chassis cost the same, the S650 provides you a "Growth Path".

SyncServer S650


SyncServer S600


The modular Microsemi SyncServer S650 combines the best of time and frequency

instrumentation with unique flexibility and powerful network/security based features.

The base Timing I/O module with 8 BNC connectors comes standard with the most

popular timing I/O signals. When more flexibility is required, the unique Microsemi FlexPort™ Technology option enables 6 of the

BNCs to output any supported signal





The Microsemi SyncServer S650i is a S650 base chassis with no GNSS receiver.

The S650i also includes a single installed Timing I/O module. All software upgrade

options are applicable except GLONASS/BEIDOU/SBAS. A detailed visual inspection of the rear of S650i will show the server does not have an antenna connection\

 The Microsemi SyncServer S80 is a fully integrated GPS/GLONASS antenna, receiver, NTP server, and Power over Ethernet (PoE) interface that easily integrates into existing PoE infrastructure to immediately be the source of accurate, secure, and reliable time stamps for all network connected devices. Network isolated physical security systems benefit as the ruggedized Stratum 1 network time server is ideal for time-synchronizing IP security cameras, access control devices, and digital/network video recorders. 

Network Time Server Side by Side Comparison


Microchip's 1U Rack Mount Time & Frequency Distribution units deliver precision reference signals to multiple equipment stations without degrading the signal or creating crosstalk. Paired with used with Microchip’s GPS receivers, frequency standards and oscillators, our time and frequency modules effectively distribute signals and generate all rates required by communication systems, satellite earth stations, test facilities and engineering laboratories.  

5071A Cesium Clock Primary Frequency Standard

Unsurpassed accuracy, stability and reliability for demanding laboratory and field applications.

Accurate, stable, and capable of delivering extremely predictable time and phase for long periods, the 5071A meets the needs of leading-edge metrology and calibration labs. Used with GPS systems, the 5071A provides master clock integration for telecommunication, satellite communication, and navigation systems.

Microchip's 5071A primary frequency standard delivers exceptional frequency stability. Thanks to a stability specification for 30-day averaging time, the 5071A can keep extremely predictable time and phase for long periods. Combined with a GPS timing receiver the 5071A primary frequency standard can produce a highly robust, inexpensive, and redundant frequency and time system. 

Key Features

1. Frequency accuracy to 5 x 10-13

he intrinsic accuracy of the cesium beam tube assures that any 5071A Option 001 will power up to within 5 x 10-13 of the accepted standard for frequency. This is achieved under full environmental conditions in 30 minutes or less- and without the need for any adjustments or alignments.

2. Long-term stability better than 1 x 10-14

The 5071A Option 001 high-performance cesium beam tube guarantees stability to be better than 1 part in 10-14 for averaging times of five days or greater. The 5071A is the first cesium standard to specify stability for averaging times longer than 100,000 seconds (approximately one day).

3. Easy to use with automatic startup and intuitive menu structure

Automatic startup is simple and requires no adjustments. A logical menu structure simplifies front-panel operations, selections, and status reporting. The 5071A can be operated and maintained anywhere. All controls are programmable, status can be checked remotely, and no adjustments or alignments are necessary during operation. An internal battery provides 45 minutes of backup in case of AC power failure 

4. Proven Reliability

 The 5071A has demonstrated an average mean time between failures (MTBF) of greater than 160,000 hours since its introduction in 1992 

5. Robust Warranty

The 5071A Standard Performance comes standard with a 2-year electronics warranty and 10-year 

tube warranty.
