Overview
The 18QHTF21-10.7386-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 10.7386 MHz and utilizes LVCMOS output logic levels. The device requires a supply voltage of 1.8V and includes an Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. This component is designed for timing applications requiring precise frequency stability in low-voltage digital circuits.
Feature Summary
- LVCMOS output interface for digital compatibility
- Integrated enable/disable functionality for power control
- Compact surface-mount package design
Applications
- Digital signal processing systems
- Communication equipment timing references
- Microcontroller clock sources
Procurement Notes
Verify the specific suffix 'OE' matches the required enable/disable configuration and voltage level. Confirm that the 1.8V supply requirement aligns with the target system's power rails. Ensure the 4-SMD no-lead footprint corresponds to the PCB land pattern specifications to guarantee proper soldering and mechanical stability during assembly processes.
Selection Notes
Select this component when a 10.7386 MHz reference is required with low voltage operation. Consider the LVCMOS output swing compatibility with downstream logic families. Evaluate the thermal performance within the specified operating temperature range. Assess the physical size constraints against the available board space for the 2.0x1.6 mm package.
Part Context
This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The 'OE' suffix indicates specific pinout or functional variations compared to other suffixes like 'PD'. It is distinct from TCXOs or VCTCXOs which offer higher stability but different cost structures.
Replacement Considerations
Direct substitutes include other 10.7386 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pin-to-pin compatibility and electrical parameters such as current consumption and start-up time before substitution.
