New oscillator challenges rubidium frequency standards

24 July 2013 Analogue, Mixed Signal, LSI

Vectron announced a new family of high-precision crystal oscillators with the release of its new Extended Holdover Crystal Oscillator (EHXO) line, specifically designed to ensure accurate timing in wireless base stations at a fraction of the price of rubidium frequency standards.

‘Holdover’ refers to the ability of the base station to maintain its performance levels through any interruption in the main network or GPS timing signal. This can occur when the satellite timing reference is susceptible to urban canyon effects or intermittent jamming, where high traffic levels make network derived timing unavailable or where the external source of timing is otherwise compromised.

The performance of the new MX–042 enables base stations to stay online and in operation even if the master timing reference is lost for up to 24 hours. The high levels of stability achieved by the device ensure that frequency and phase budgets are maintained, allowing the base station to continue to function normally even in the absence of its main timing reference.
