Most applications rely on Global Navigation Satellite Systems (GNSS) to provide precise time and frequency, but GNSS is susceptible to jamming and spoofing attacks.
Microchip’s 5071B is the next-generation commercial caesium clock to the existing 5071A and is available in a three-unit height (3U) 19-inch rackmount enclosure, providing a compact product to work in environments where it can be easily transported and secured versus a larger alternative designed specifically for laboratory environments.
The 5071B has upgraded electronic components to address possible obsolescence or non-RoHS circuitry. It provides 100 ns holdover for more than two months, maintaining system synchronization when GNSS signals like GPS are denied. For example, this capability would enable a 5G network to remain fully operational for months without GNSS.
As a caesium beam tube product with no deterministic long-term frequency drift, the 5071B provides absolute frequency accuracy of 5E-13 or 500 quadrillionths over all specified environmental conditions for the life of the product.
For military applications requiring rapid deployments for system radars, 5E-13 stability eliminates the need for the acquisition of external synchronisation sources prior to radiating. In satellite communications, this enables the user to broadcast and transmit over very small frequency bands without drifting out of band for the entire duration of the product.
The 5071B is fully compliant with the Restriction of Hazardous Substances Directive (RoHS), which means it is available in regions where regulatory policies are in place.
