Overview
The 18QHTF21-12.386304-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 12.386304 MHz and utilizes an LVCMOS output interface. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function to reduce consumption when inactive. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.
Feature Summary
- Supports low-voltage operation at 1.8V
- Integrates a standby mode for power management
- Provides LVCMOS signal output compatibility
Applications
- Embedded systems requiring precise clock timing
- Consumer electronics with space constraints
- Industrial control modules
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply rail is stable within the operational limits specified in the official datasheet. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to guarantee proper soldering and mechanical stability during assembly.
Selection Notes
Select this component when a small form factor and low power consumption are critical. The 1.8V operating voltage makes it suitable for modern portable devices. Consider the LVCMOS interface compatibility with your microcontroller or FPGA inputs. The integrated power-down feature aids in extending battery life in portable applications.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on surface-mount quartz oscillators. The series offers various frequencies and packages, catering to diverse electronic design needs. The 'PD' suffix indicates the inclusion of a power-down capability, distinguishing it from standard continuous-operation variants within the same family.
Replacement Considerations
Direct substitutes must match the 12.386304 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics with alternative manufacturers if sourcing changes are necessary.
