Frequently Asked Questions
What frequency stability does the OX-2022-EAE-1080-25M0000000 achieve, and why does it matter for network synchronization?
The OX-2022-EAE-1080-25M0000000 achieves ±10 ppb (parts per billion) frequency stability, which is critical for SDH, SONET, and Ethernet synchronization applications where even small frequency errors accumulate into timing slip over millions of clock cycles. This stability level supports Stratum 3 and better network timing requirements.
How does the OCXO design of OX-2022-EAE-1080-25M0000000 outperform a TCXO in precision timing applications?
Unlike a TCXO that compensates temperature with a correction circuit, the OX-2022-EAE-1080-25M0000000 places the crystal in a temperature-controlled oven maintaining a constant internal thermal environment, achieving ±10 ppb stability versus typical TCXO values of ±0.5 ppm to ±2.5 ppm. This 50x to 250x improvement in frequency accuracy is essential for GPS disciplined oscillators and telecom reference clocks.
What supply voltage and temperature range does the OX-2022-EAE-1080-25M0000000 support for industrial deployments?
The OX-2022-EAE-1080-25M0000000 operates from a 3.3 V supply and covers an industrial temperature range of -40°C to +85°C. This makes it suitable for outdoor base stations, avionics, and industrial test equipment exposed to wide ambient temperature swings while maintaining ±10 ppb output accuracy at 25 MHz.
Which applications benefit most from specifying the OX-2022-EAE-1080-25M0000000 at 25 MHz rather than a higher-frequency OCXO?
Applications that require a 25 MHz reference directly compatible with FPGA PLL input clocks, microprocessor system clocks, or network synchronization ICs benefit from specifying the OX-2022-EAE-1080-25M0000000 at 25 MHz. Higher-frequency OCXOs require additional divider circuitry, adding phase noise and complexity; the 25 MHz output with ±10 ppb accuracy feeds directly into most IEEE 1588 PTP clock recovery circuits without extra hardware.
For a compact GNSS receiver design, how does the 3.3 V supply and small footprint of this OCXO simplify system integration?
The 3.3 V supply of the OX-2022-EAE-1080-25M0000000 is directly compatible with modern digital logic rails, eliminating the 5 V level-shift circuitry needed for older OCXO modules. Combined with a compact SMD package, it can be placed close to the GNSS signal processing IC, minimizing trace length and phase noise contribution from a 25 MHz reference path.
