Overview
The u-blox LEA-M8F module is a standalone GNSS time and frequency reference product featuring the high
performance u-blox M8 positioning engine. The device provides multi-GNSS synchronization 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 (network listen), Synchronous 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 providing 100 ppb autonomous hold-over. An external TCXO or OCXO can also be
measured and controlled 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
interface. This allows measurements from macro-sniff, Synchronous Ethernet or packet timing to be combined
with measurements from GNSS.
The industry standard LEA form factor in the leadless chip carrier (LCC) package makes the LEA-M8F easy to
integrate, while combining exceptional timing and frequency performance with highly flexible design and
connectivity options. SMT pads allow fully automated assembly with standard pick & place and reflow-soldering
equipment for cost-efficient, high-volume production enabling short time-to-market.
