XO5083-009R

Overview

The MtronPTI XO5083-009R is a surface-mount Oven Controlled Crystal Oscillator (OCXO) housed in a standard 1x1 inch (25.4 x 25.4 mm) package. It operates on a 12V supply and utilizes an SC-cut crystal to ensure high frequency stability and low aging rates suitable for precision applications. The device provides a sine wave output, which is typically optimized for driving RF mixers or phase-locked loops without additional amplification stages. Designed for compact form factors, it replaces larger through-hole OCXOs while maintaining superior thermal regulation and long-term stability characteristics required in critical timing systems.

Feature Summary

• SC-cut crystal construction for optimal temperature drift and aging performance
• Sine wave output configuration suitable for direct RF signal generation
• Surface mount design reduces PCB footprint compared to traditional through-hole variants
• Integrated oven control ensures stable operation across wide temperature ranges

Applications

• Portable short-range microwave radio local oscillators
• Small base station synchronization and clock sources
• Frequency reference for portable test and measurement instruments
• High-stability RF links requiring minimal environmental compensation

Procurement Notes

Verify the specific suffix '009R' against the official MtronPTI datasheet to confirm the exact frequency and pinout configuration. Ensure the 12V power supply requirement is compatible with your system design, as this differs from the common 5V variants. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the pin definitions carefully, as markings may not be visible on the component body.

Selection Notes

Select this model when space constraints prohibit the use of larger through-hole OCXOs but high stability is still required. The sine wave output is ideal for analog RF chains, whereas HCMOS outputs are better for digital logic interfaces. Consider the SC-cut variant over AT-cut if long-term aging and temperature stability are critical priorities for the application environment.

Part Context

The XO5083 series represents MtronPTI's line of compact, surface-mount OCXOs designed to bridge the gap between standard TCXOs and bulky traditional oven-controlled units. This series allows engineers to achieve oven-level stability in small form-factor designs. The XO5083-009R specifically falls into the high-stability category using SC-cut crystals, targeting applications where size reduction is necessary without compromising frequency accuracy.

Replacement Considerations

Direct replacements must match the 1x1 inch SMT footprint and 12V supply voltage. Verify that substitute parts offer comparable sine wave output amplitude and phase noise specifications. Ensure the replacement supports SC-cut technology if long-term stability is a key requirement. Check pin compatibility, particularly for the frequency adjustment and enable functions.
