LEA-M8F module: u-blox M8 GNSS time & frequency reference module
■ Concurrent reception of GPS/QZSS, GLONASS, BeiDou
■ Integral disciplined low phase noise 30.72 MHz system reference oscillator
■Accurate measurement and control of external oscillators
■ Industry leading acquisition sensitivity and single-satellite timing
■ Autonomous 100 ppb hold-over, all effects, including full operating temperature range
■Prepared for integration with external PTP, Sync-E and network listen
●Product description:
■u-blox time and frequency products provide multi-GNSS synchronisation for cost-sensitive network edge equipment including Small Cell and Femto wireless base-stations. The LEA-M8F module is a fully self-contained phase and frequency reference based on GNSS, but can also be used as part of a complete timing sub-system including macro-sniff Synchro-nous Ethernet and packet timing.
■The LEA-M8F module includes a low-noise 30.72 MHz VCTCXO meeting the master reference requirements for LTE Small Cells and provides 100 ppb autonomous hold-over across its full operating temperature range. The LEA-M8F module can also measure and control an external TCXO or OCXO for TD-LTE, LTE Advanced and other applications requiring extended hold-over. External sources of synchronization are supported through time-pulse and frequency inputs and a message inter-face. This allows measurements from macro-sniff, Sync-E or packet timing to be combined with measurements from GNSS.
■The u-blox time and frequency products include timing integ-rity alarms that report phase and frequency uncertainty both during normal operation and hold-over. They feature a high dynamic range radio with both analog and digital interference mitigation, supporting their inclusion as an integral part of a local area base station design.
