Overview
The 18QHTF21-124.444-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 124.444 MHz. It utilizes LVCMOS output logic and supports a supply voltage range compatible with 1.8V operation. The device features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals in electronic circuits.
Feature Summary
- LVCMOS output logic for digital interface compatibility
- Integrated enable/disable control functionality
- Compact 4-SMD no-lead surface mount package
Applications
- Digital signal processing systems
- Communication equipment clocking
- Embedded system timing references
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the OE suffix with manufacturer documentation to confirm any specific ordering or packaging variations.
Selection Notes
Select this component when a 124.444 MHz reference signal is required with low-power LVCMOS outputs. Consider the enable/disable feature if dynamic power saving is necessary. Evaluate the 4-SMD package size against available board space. Compare performance metrics such as phase noise and stability against alternative oscillators from other manufacturers if stricter specifications are needed.
Part Context
This part belongs to the Mercury Electronics XO series, which includes various frequencies and packages. The 18QHTF21 prefix indicates a specific family of surface-mount oscillators. Similar models include variants with different frequencies like 13.5444 MHz or 44.3417 MHz within the same package type.
Replacement Considerations
Direct substitutes may include other 124.444 MHz LVCMOS oscillators in 4-SMD packages from manufacturers like Epson, SiTime, or TXC. Verify pinout compatibility and electrical parameters before substitution.
