M61112JTSN 21.000000

Overview

The M61112JTSN 21.000000 is a surface-mount HCMOS output clock oscillator manufactured by MtronPTI, housed in a ceramic leadless package with ten terminals and physical dimensions of 7.0mm x 5.0mm x 2.0mm. It operates at a nominal frequency of 21 MHz within an industrial temperature range of -40 °C to +85 °C. The device supports RoHS compliance and features a tri-state function for enable/disable control. Electrical specifications include a maximum rise and fall time of 8 ns, a frequency stability of 0.3%, and an aging rate of 2 PPM per first year.

Feature Summary

• Provides tight frequency stability over wide industrial temperature ranges
• Features low phase noise and excellent G-sensitivity performance
• Supports tri-state functionality for power management

Applications

• WiMax base stations
• Military and avionics systems
• Point-to-point and multi-point radios
• Test and measurement equipment
• GPS receivers

Procurement Notes

Verify the specific suffix JTSN against official MtronPTI documentation to confirm pinout configuration and voltage compatibility. Ensure the ordering part number matches the required frequency tolerance and aging specifications. Confirm that the ceramic leadless package variant aligns with your PCB footprint requirements. Cross-reference the RoHS compliance status with current regulatory standards for your target market.

Selection Notes

Select this component when precise timing is required for digital signal processing or communication interfaces. The HCMOS output level ensures compatibility with standard logic families. Consider the 7x5 mm package size for space-constrained designs. Evaluate the 0.3% stability requirement against system jitter budgets. Verify that the operating temperature range meets environmental conditions.

Part Context

This model belongs to the M611x Series of precision TCXOs and TCVCXOs from MtronPTI. The series is designed for applications requiring low voltage operation and high stability. These oscillators utilize specially processed crystals to achieve tight stability over temperature and time. The family includes various output types and frequency options for diverse electronic systems.

Replacement Considerations

Direct substitutes within the M611x series may offer different frequencies or voltage versions. Verify mechanical dimensions and pin assignments before replacement. Check if alternative models provide improved aging rates or stability metrics. Ensure any substitute maintains the same HCMOS output characteristics and package type.
