Overview
The 18QHTF21-64.480-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 64.48 MHz and utilizes LVCMOS output logic. The device functions on a 1.8V supply voltage and includes an enable/disable control feature. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.
Feature Summary
- Supports enable/disable functionality for power management
- Utilizes LVCMOS output logic for digital interface compatibility
- Designed for low-profile surface-mount applications
Applications
- Consumer electronics requiring precise clock signals
- Industrial control systems
- Communication equipment timing circuits
Procurement Notes
Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm enable/disable pin configuration and voltage levels. Ensure the 2.0x1.6mm footprint matches the target PCB design. Cross-reference the 64.48 MHz frequency requirement with system specifications to avoid timing errors.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a small form factor. The enable/disable feature makes it suitable for battery-powered devices needing power optimization. Confirm that the LVCMOS output swing meets the input requirements of the downstream logic circuitry.
Part Context
Mercury Electronics Ind. Co. Ltd is a Taiwan-based manufacturer specializing in frequency control products since 1973. The 18QHTF series represents their line of standard crystal oscillators designed for various electronic applications requiring stable timing sources.
Replacement Considerations
Check for direct substitutes within the 18QHTF series from Mercury Electronics offering identical 2.0x1.6mm packages and 1.8V operation. Verify that any alternative maintains the same LVCMOS output type and enable/disable functionality.
