GNSS-Based Synchronisation Solutions Introduction LTE-A and LTE-TDD cellular network technologies require phase alignment at base stations. The current 3GPP requirement is as low as ±1.5 µs at base stations, though new versions of interference mitigation and location services push the requirements down to less than 0.5 µs. GNSS-based synchronisation technologies are key to the implementation of such systems. Rakon offers a wide variety of timing references for GNSS-based synchronisation systems. Rakon’s GNSS Based Synchronisation Markets and Applications GNSS modules for Synchronisation systems Grand Master Timing solutions Edge Grand Master solutions Small Cell solutions Micro and Pico Base Station solutions Long Term Holdover modules (Guaranteed 1.5 µs/24 – 72 hours) Rakon Advantages Cutting Edge TCXO Technology Rakon’s in-house developed Pluto+™ ASIC powers world class TCXO technology, providing tight temperature stability (±50 – 500 ppb), very low phase noise (20 MHz, -130 dBc/Hz @100Hz), excellent temperature sensitivity (10 ppb/°C), and very low power consumption (20 mW). The superior performance of Rakon’s Pluto+™ based products enables the development of competitively priced, high performance timing and synchronisation solutions. World’s First IC-Based OCXO Technology SMART OCXO Technology Rakon’s Mercury™ ASIC has made possible the smallest (14 x 9 mm and 9 x 7 mm), lowest power consuming (350 mW) and most reliable (FIT of < 50) OCXOs in the industry. The Mercury+™ OCXO enables applications that require high frequency stability (<±5 ppb) with low profile and power. Rakon’s extensive experience and knowledge in the Frequency Control Product (FCP) domain enabled the ability to add SMART technologies to the oscillator solutions by compensating for temperature variations, aging, hysteresis, power supply variations and other system effects. These high end OCXOs feature temperature stabilities of <0.2 ppb over the operating temperature range and <0.05 ppb/day aging. These OCXOs also offer digital control, which reduces unwanted noise in the system and eliminates analogue design complexities.
