NEO-M8T-0

RF Receivers Overview

The u-blox NEO-M8T-0 is a surface-mount GNSS timing module designed for high-precision time synchronization. It supports multi-GNSS constellations including GPS, GLONASS, Galileo, and BeiDou. The module delivers a precision reference clock with accuracy less than 20 nanoseconds. It features Receiver Autonomous Integrity Monitoring (RAIM) and continuous phase uncertainty estimation for enhanced reliability. The receiver offers high sensitivity of -167 dBm acquisition sensitivity. It provides two configurable time pulse outputs ranging from once per minute to 10 MHz. The module measures 12.2 x 16.0 mm.

RF Receivers Feature Summary

• Integrates Receiver Autonomous Integrity Monitoring (RAIM) and continuous phase uncertainty estimation for high integrity timing.
• Generates precise reference clocks with sub-20 nanosecond accuracy derived from multi-GNSS signals.
• Outputs multi-GNSS RAW data including carrier phase, code phase, and pseudo-range measurements.
• Supports low duty cycle operation to optimize power consumption for battery-powered applications.

RF Receivers Applications

• Mobile communication network infrastructure synchronization
• Power generation and distribution system timing
• Seismometer arrays for earthquake field measurement

RF Receivers Procurement Notes

Verify the specific suffix against official u-blox documentation to confirm supported constellations and firmware version. Ensure the supply chain source provides genuine components with valid traceability. Confirm that the receiving equipment supports the required 3.3V logic levels and interface protocols. Check for any regional regulatory compliance requirements relevant to GNSS receivers in the target deployment area.

RF Receivers Selection Notes

Select this module when sub-20 nanosecond timing accuracy is required alongside high reliability. It is suitable for environments where signal visibility may be limited due to its high sensitivity. Consider the LCC package size if board space is constrained compared to larger LEA variants. Evaluate power budget constraints as the module supports low duty cycle modes for extended battery life in remote deployments.

RF Receivers Part Context

The NEO-M8T-0 belongs to the u-blox M8 series of concurrent GNSS timing modules. It succeeds previous PPS timing modules while maintaining pin compatibility for easier upgrades. The module complements the frequency reference capabilities of the LEA-M8F series. It is part of a family designed to meet strict requirements for reliability, precision, and low power consumption in critical infrastructure applications.

RF Receivers Replacement Considerations

The LEA-M8T serves as a compatible alternative within the same product family, offering similar timing functions in a different package size. Both modules share functional similarities but differ in physical dimensions and potentially specific feature sets. Verify pinout compatibility and software configuration requirements when transitioning between these variants to ensure seamless integration into existing designs.
