The OTA Mini delivers lab-grade precision in a compact, portable form factor, combining a high-stability DOCXO with an optional integrated battery. Designed for field testing, broadcast and media production, and remote or temporary deployments, it provides reliable reference timing for on-site validation, live and distributed workflows, and hard-to-reach locations—ensuring accurate synchronization wherever traditional timing appliances fall short.
Why the Open Time Appliance Mini?
-
Unmatched Precision
Nanosecond accuracy ensures all downstream devices align to a single authoritative time. Crucial for finance, telecom, power grids and broadcasting.
-
Enterprise Performance in Miniature Form
Delivers the power of a full-scale grandmaster clock in a compact, rugged device that fits anywhere—without sacrificing reliability.
-
Zero-Configuration Deployment
Eliminates manual configuration with intelligent self-adjusting technology that maintains perfect sync across all connected devices.
-
Universal Compatibility
Seamlessly integrates with both PTP and NTP environments, making it the most adaptable time source for modern infrastructure.
