Holdover Reference Oscillator
OX-203
Description
The Holdover Reference Oscillator family is designed specifically to meet the need for a high accuracy cost effective backup
reference.
These high stability oscillators will provide consistent, repeatable, extended holdover to the stated phase accuracy - making them
ideal for applications where GPS, 1588 or other sources of timing are intermittent or prone to extended periods of unavailability.
Features
Applications
• Available in 8 hour and 24 hour version
• Holdover accuracy available to ≤8μs and ≤1μs
• Specifically designed for inter-operability with existing designs
based on conventional OCXO’s.
• Advanced digital compensation techniques take place inside
the Holdover Reference - no need for programming or other user
intervention.
• Precision Timing Applications in:
• Wireless Base Stations
• Wireless Backhaul
• Digital Video Broadcast
• Low latency optical networking
• Power distribution
• Test and Measurement
