Precision timing GNSS module for cellular networks

Swiss-based u‑blox has unveiled the LEA-M8F precision timing GNSS module. The compact, surface-mount module generates a precise 30.72 MHz reference clock crucial for synchronizing 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, LEA-M8F is able to acquire and track all 50+ GPS, GLONASS and BeiDou satellites. High sensitivity and aided GNSS option enables quick autonomous start-up even inside structures with limited sky-view. “A reliable, compact and cost-effective precision reference clock is a crucial component used in many systems in the Critical Infrastructure and Key Resource sectors (CIKR),” said Thomas Nigg, Vice President of Product Marketing at u-blox, “Our LEA-M8F GPS/GNSS satellite-disciplined timing module enables the proper operation of many mission-critical infrastructure systems including mobile and fixed-line communication networks, power generation and distribution systems, gas and chemical processing plants, banking, postal and goods distribution processes.” Measuring only 17 x 22 mm, the LEA-M8F module includes a low-noise 30.72 MHz VCTCXO (voltage and temperature controlled oscillator), meeting the master reference requireme...
