LEA-M8F timing GNSS modules

High-Precision Time & Frequency Synchronization with LEA‑M8F

The u‑blox LEA‑M8F GNSS Timing Module is a fully integrated solution for precise time and frequency reference. Supporting GPS, GLONASS, and BeiDou, it features a highly stable 30.72 MHz VCTCXO (Voltage-Controlled Temperature-Compensated Crystal Oscillator) synchronized by GNSS. With excellent sensitivity of -165 dBm and an autonomous hold-over of 100 ppb, the LEA‑M8F is ideal for telecom, industrial automation, and IoT timing applications.
