Preliminary
OX-202
Oven Controlled Crystal Oscillator
OX-202
Description
The OX-202 is part of a series of oscillators specifically designed to support Timing Over Packet applications, in particular 1588-
2008 based frequency and phase reference systems. The OX-202 is stratum 3E compliant.
Features
• Available in three standard frequencies (10MHz,
12.8MHz and 20MHz)
• Excellent temperature stability
• Superior long term stability
• Optimized to support Timing Over Packet applications
• Stratum 3E compliant according to GR1244
Applications
• SETS clock support
• Wireless Base Stations
• Edge and Core Routers
