Precision timer for cellular networks

12 March 2014 Analogue, Mixed Signal, LSI

u-blox’ new LEA-M8F precision timing GNSS module generates a precise 30,72 MHz reference clock crucial for synchronising industrial data and communication systems such as small, femto and macro-cell mobile networks. High accuracy is achieved by disciplining a local oscillator or other clock source with timing signals received from satellite-hosted atomic clocks. To ensure satellite availability, the chip is able to acquire and track all 50+ GPS, GLONASS and BeiDou satellites. High sensitivity enables quick autonomous startup even inside structures with limited sky-view. Measuring 17 x 22 mm, LEA-M8F includes a low-noise 30,72 MHz VCTCXO and meets the requirements for LTE small cells as well as TD-LTE, LTE-Advanced and more.
