1380100-004

Overview

The CTS-Frequency Controls 1380100-004 is a high-performance Oven-Controlled Crystal Oscillator (OCXO) operating at a nominal frequency of 20.0000 MHz. It utilizes HCMOS output logic and requires a supply voltage range starting from 3.135 V. The device features exceptional frequency stability of ±10 ppb, classifying it as Stratum 3 compliant. Designed for through-hole mounting, the oscillator ensures reliable timing performance across an extended industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides oven-controlled stability with ±10 ppb accuracy
• Complies with Stratum 3 timing standards
• Features HCMOS output signal compatibility
• Operates within an extended industrial temperature range

Applications

• Telecommunications base station synchronization
• Stratum 3 network timing equipment
• Precision test and measurement instrumentation
• High-stability clock distribution systems

Procurement Notes

Verify that the target application supports through-hole mounting technology, as this component is not designed for surface-mount processes. Confirm that the power supply circuitry can maintain the minimum input voltage of 3.135 V under all load conditions. Ensure thermal management strategies account for the internal oven heating requirements inherent to OCXO designs during operation within the specified -40°C to +85°C environment.

Selection Notes

Select this model when strict frequency stability below ±100 ppb is required, distinguishing it from standard TCXOs or HCXOs. The Stratum 3 classification makes it suitable for primary reference clock applications in telecom infrastructure. Consider the physical size constraints associated with through-hole packages compared to modern SMD alternatives. Verify that the HCMOS output swing matches the input requirements of the downstream digital logic circuits.

Part Context

This part belongs to the CTS OCXO product line, which focuses on delivering high-frequency stability in compact form factors. Unlike standard crystal oscillators, OCXOs maintain constant temperature for superior long-term stability. The 1380100-004 specifically targets applications requiring Stratum 3 performance levels, bridging the gap between lower-cost TCXOs and larger laboratory-grade standards.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Alternative selection requires matching Stratum 3 compliance, 20 MHz frequency, ±10 ppb stability, and through-hole packaging specifications.
