Overview
The 18QHTF21-11.060472-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 11.060472 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 package with dimensions of 2.0x1.6 mm, designed for surface-mount applications.
Feature Summary
- Standard crystal oscillator configuration with LVCMOS output interface
- Integrated enable/disable functionality for power control
- Compact 4-SMD no-lead surface mount package design
Applications
- Digital signal processing circuits requiring precise clock timing
- Embedded systems utilizing low-voltage logic interfaces
- Portable electronic devices constrained by space and power requirements
Procurement Notes
Verify the specific suffix against official documentation to confirm operational mode. The OE suffix indicates an Enable/Disable pin configuration, distinct from other variants like PD which may imply Power Down functionality. Ensure the required supply voltage and load conditions match the system design specifications before procurement to avoid compatibility issues.
Selection Notes
Select this component when a stable 11.060472 MHz reference is needed with active power control capabilities. The 1.8V operating range suits modern low-power digital environments. Consider the physical footprint constraints of the 2.0x1.6 mm package during PCB layout planning to ensure adequate clearance and thermal performance.
Part Context
Mercury Electronics Ind. Co. Ltd specializes in frequency control products, including quartz crystals and oscillators. This model belongs to their series of surface-mount oscillators designed for consumer and industrial electronics. The company has a long history in Taiwan's quartz industry, focusing on precision timing solutions.
Replacement Considerations
Direct substitutes must match the 11.060472 MHz frequency, 1.8V supply, LVCMOS output, and Enable/Disable function. Verify that alternative packages maintain the 2.0x1.6 mm form factor. Cross-reference datasheets to ensure identical electrical characteristics and pinout configurations.
