Description:
GPTiMeâ„¢ is a digital PLL with a GPS receiver that performs the
special signal processing required for delivering the output
frequencies free of the input impairments (such as jitter, wander,
On/Off and phase hits) as per the Telcordia, ITU-T and IS-95
standards.
Based on TeraSync’s internationally acclaimed ATiMe platform,
GPTiMeâ„¢ is the most advanced unit available in the marketplace
today, providing a unique ability to lock onto the back-haul
signal and the GPS signal as well as combining both of these
signals for perfect phase and frequency accuracy.
It is equipped with a GPS receiver used for obtaining GPS satellite
transmissions from which a jittered 1PPS signal is derived.
GPTiMeâ„¢ locks onto the derived GPS signal, enabling the synchronization
of a base station to GPS/UTC time.
Temperature and Aging Compensation Special (Patent Pending) Algorithm will enable using a low cost oscillator to achieve a HoldOver Accuracy of a double Oven 10E-10 -in a very low cost manner.
The Back Haul inputs can be either T1/E1 (and T12), or an IEEE 1588 or TeraSync proprietary solution.
It can serve as a 1588 Master Clock using the GPS signals and a slave clock as well.
GPTiMe can serve the whole range of Wireless methods, CDMA2000, GSM, UMTS and WiMax - with a HoldOver Time Keeping of 2.5 microsecond through 50 microsecond for up to 10 hours depending on the customers various needs.
GPTiMe is available with 10MHz, 2.048MHz and 1PPS outputs as well as others that can be provided upon request.
For WiMAx Stand loan Sync station –the GPTiMe module is available from the shelf with any required accuracy.
