Overview
The 18QHTF21-107.520-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 107.52 MHz and utilizes an LVCMOS output logic level. The component is designed for operation with a supply voltage of 1.8V and features an Enable/Disable control function. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.
Feature Summary
- Standard XO oscillator design providing reliable clock signals
- Integrated Enable/Disable functionality for power management
- LVCMOS output interface compatible with digital logic circuits
Applications
- Digital signal processing systems
- Communication equipment timing references
- Embedded system clock generation
Procurement Notes
Verify the specific manufacturer designation, as sources list both Mercury Electronics Ind. Co. Ltd and Mercury United Electronics, Inc. Ensure the ordering suffix matches the required enable/disable configuration. Confirm the package type is 4-SMD No Lead and the voltage is strictly 1.8V before procurement to avoid compatibility issues.
Selection Notes
Select this component when a 107.52 MHz reference is required with low-voltage 1.8V operation. The LVCMOS output is suitable for direct interfacing with standard digital inputs. Consider the Enable/Disable feature if power conservation or clock gating is necessary for the application design.
Part Context
This part belongs to the 18QHTF series of surface-mount oscillators from Mercury Electronics. The series typically includes various frequencies and voltage options. The 18QHTF21 variant specifically denotes the 1.8V supply version with the OE suffix indicating the presence of an enable pin for control.
Replacement Considerations
The 18QHTF22-107.520-OE is a related part number within the same series, potentially differing in package dimensions or specific electrical tolerances. Verify pinout and mechanical footprint compatibility before substituting.
