PRECISION TIMING FOR REAL-WORLD SYSTEMS
AION H10 Precision Timing Reference for Raspberry Pi
AION Timing develops high-performance precision timing and frequency-reference technology for engineers, laboratories, RF and SDR applications, embedded systems, industrial applications, research, and other systems where accurate, stable timing matters.
Â
Our first product, the AION H10, brings precision OCXO-based timing to the Raspberry Pi platform, combining a high-stability frequency reference, 1 PPS synchronization, intelligent calibration and disciplined operation with precision holdover in a compact HAT architecture.
Â
Engineered around a premium SiTime OCXO, the H10 is designed for applications requiring a stable 10 MHz reference, with application-specific OCXO frequency configurations from 10–60 MHz available for qualified requirements.

10 MHz Reference • Precision 1 PPS • OCXO Holdover • Custom 10–60 MHz Configurations
HARDWARE + SOFTWARE
One Complete Timing Platform
Every AION H10 includes AION software designed to simplify configuration, monitoring, calibration and timing control. The H10 hardware and software are developed together so users can focus on their application instead of building oscillator-control and timing-management software from scratch.
INSTALL
Mount the H10 on a compatible Raspberry Pi 4/5, CM4/5
MONITOR
View timing status, calibration and reference information.
CONFIGURE
Install and configure the supplied AION software.
OPERATE
Use the H10 as the precision timing foundation for your application.
INTELLIGENT TIMEKEEPING
Precision While Powered. Timekeeping While Off.
The H10 uses two timing technologies for different purposes. The precision SiTime OCXO provides the high-stability operating frequency reference and holdover capability while the system is powered. A dedicated DS3231 real-time clock preserves calendar date and time while the Raspberry Pi is powered down. The H10 architecture is designed to characterize RTC drift so known error can be compensated when the system returns to operation, improving time continuity across power cycles.

RECALIBRATABLE PRECISION
Every H10 is factory calibrated before shipment and can be recalibrated against a supported precision reference in the field to compensate for oscillator aging and long-term drift—without returning the unit to the factory.
FLEXIBLE BY DESIGN
Multiple Paths to Precision
The H10 is designed so precision timing does not depend permanently on a single external reference. It can be calibrated and disciplined using supported precision timing references and then continue operating from its onboard OCXO when that reference is removed or unavailable.
EXTERNAL 1 PPS
Connect a compatible precision 1 PPS source when synchronization or calibration is required.
OCXO HOLDOVER
Continue operating from the onboard OCXO when the external timing reference is unavailable.
