Overview
The 18QHTF21-13.553-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.553 MHz and utilizes LVCMOS output logic levels. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, No Lead surface-mount package, suitable for space-constrained electronic designs requiring precise timing signals.
Feature Summary
- LVCMOS output interface for digital logic compatibility
- Integrated enable/disable pin for power control
- Standard quartz-based frequency stability
Applications
- General-purpose digital circuit timing
- Embedded system clock sources
- Consumer electronics signal processing
Procurement Notes
Verify the specific suffix '-OE' against the manufacturer's current datasheet to confirm the exact enable/disable functionality and tolerance specifications. Ensure the 1.8V operating voltage aligns with the target system's power rails before integration. Cross-reference the 4-SMD no-lead package dimensions with PCB footprint libraries to guarantee mechanical fit.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable/disable feature makes it suitable for battery-powered applications where power conservation during idle states is critical. Consider the 13.553 MHz frequency specifically if it matches the required baud rate or clock division ratios for the target application.
Part Context
This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a standardized small outline package. The '18' prefix likely indicates the 1.8V supply variant, distinguishing it from other voltage versions in the same product family.
Replacement Considerations
Direct substitutes must match the 13.553 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify that any alternative component supports the enable/disable control function if power management is required in the design.
