The NFS-220 is a low cost precision time and frequency standard that uses GPS for use in WI-FI, Wi-Max, satellite communications, telecommunications, and military communications. This frequency standard is the newest of Brandywine’s GPS Synchronizing clocks and utilizes a high performance 16 channel receiver with automatic position-averaging that enables the best use of GPS when operating in a fixed location. The NFS220 includes 4 low phase noise 10MHz outputs, 4 1PPS outputs with individual 600PS propagation delay compensation, IRIG, Have Quick, and NTP outputs.
The NFS220 is fitted with an internal back up oscillator that is continuously calibrated to GPS using an advanced algorithm, providing optimal frequency control of the oscillator. This ensures that the highest time and frequency accuracy is maintained if no satellites can be tracked, and ensures an ultra stable, low noise frequency reference.

This ensures that the highest time and frequency accuracy is maintained if no satellites can be tracked, and ensures an ultra stable, low noise frequency reference.
The basic NFS220 includes a precision OCXO frequency standard, while a Rubidium oscillator is optionally available to give a variety of price and performance options. An option with a low noise OCXO phase locked to a rubidium is also available, combining the low noise characteristic with the OCXO with the long-term stability of a rubidium.
The NFS220 provides “at a glance” status indication via front panel LED’s and can be integrated with other management systems using Ethernet and serial ports.
The NFS220 provides simple integration into military platforms by allowing synchronization from Have Quick time code, which is available on military SA-ASM GPS receivers such as the DAGR or PLGR. The NFS220 also generates Have Quick and 1PPS signals compatible with ICD-GPS-060.
The integrated Ethernet interface provides Network Time Protocol (NTP) synchronization of other connected computers.
In addition to NTP, the NFS220 Ethernet interface contains a built in web server that allows the NFS220 to be controlled using a standard web browser such as Internet Explorer. Simple Network Management Protocol (SNMP) allows easy integration of the NFS220 with industry standard network management systems.
The NFS220 provides three 1PPS time mark outputs. A unique feature allows precisely controlled delays to be inserted into these outputs to compensate for cable and other propagation delays. Compensation delay is independent for each output and has Serial time code outputs are provided to allow time synchronization to be distributed to computers, displays, and other equipment requiring precision time. Two outputs are dedicated to Have Quick time code. Two outputs (one modulated, one DC level shift) may be user selected from IRIG A, IRIG B, IRIG E, IRIG G.
Four low phase noise 10 MHz sine wave outputs from the disciplined oscillator are provided. Signal amplitude is software settable.
All outputs are provided with activity detectors. Loss of any output is indicated by means of a individual front panel alarm LED as well as through the network interface or a discrete alarm output.
