XO5083-008R

Overview

The XO5083-008R is a surface-mount oven-controlled crystal oscillator (OCXO) manufactured by MtronPTI. It operates at a nominal frequency of 10.0 MHz with a supply voltage of 12V. The device features an SC-cut crystal and provides a sine wave output. Key stability parameters include a frequency tolerance of ±20 ppb and a typical phase noise of -150 dBc/Hz at 1 kHz offset. The unit achieves thermal stabilization within three minutes at 25°C, making it suitable for applications requiring rapid warm-up and high frequency precision in compact form factors.

Feature Summary

• SC-cut crystal construction ensures superior long-term aging performance and temperature stability compared to AT-cut alternatives.
• Sine wave output capability allows direct interfacing with mixers and phase-locked loops without additional amplification stages.
• Surface-mount package design significantly reduces board space requirements while maintaining the thermal isolation of an ovenized system.

Applications

• Local oscillators for short-range microwave radio systems
• Frequency references for portable test and measurement instruments
• Synchronization sources for small base station infrastructure

Procurement Notes

Verify the specific ordering suffix to confirm the required output type and cut. The XO5083 series includes variants with HCMOS outputs or different supply voltages; ensure the selected part matches the circuit's power and logic requirements. Confirm that the 12V supply specification aligns with the system design before procurement.

Selection Notes

Select this component when space constraints prohibit through-hole OCXOs but high stability is mandatory. The SC-cut variant offers better aging characteristics than AT-cut versions. Ensure the design accommodates the 12V supply requirement and the thermal management needs associated with ovenized operation in a surface-mount footprint.

Part Context

This model belongs to the XO508x series of 1-inch surface-mount OCXOs from MtronPTI. The series is engineered for applications demanding high stability in compact designs. The XO5083 specifically denotes the SC-cut configuration with sine wave output, distinguishing it from other family members that may offer digital outputs or AT-cut crystals.

Replacement Considerations

Direct replacements are limited due to the specific surface-mount OCXO form factor. Verify compatibility with existing footprints and thermal profiles. Alternative solutions may require redesigning the PCB layout and power supply architecture if switching to different package types or voltage requirements.
