Overview
The 18QHTF21-81.0372-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 81.0372 MHz with an LVCMOS output signal. The device requires a 1.8V supply voltage and supports a Standby (Power Down) function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.
Feature Summary
- LVCMOS output interface
- Standby (Power Down) capability
- Compact 4-SMD No Lead package
Applications
- Low voltage digital systems
- Portable electronic devices
- Communication equipment requiring precise timing
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD No Lead package footprint matches your PCB layout constraints to avoid assembly issues.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS output. The integrated standby feature makes it suitable for battery-powered applications where power conservation is critical. Verify that the 81.0372 MHz frequency meets the specific clocking needs of the target application.
Part Context
This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies within a small 2.0x1.6 mm footprint. The -PD suffix typically indicates the inclusion of a power-down control pin or functionality, distinguishing it from standard continuous-operation variants.
Replacement Considerations
Direct replacements must match the 81.0372 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify compatibility of the standby control logic if present. Cross-reference with other manufacturers offering similar low-profile XO components with identical electrical specifications.
FAQ
Does the 18QHTF21-81.0372-PD support power down?
Yes, the datasheet description indicates it features a Standby (Power Down) function.
What is the output type of this oscillator?
The output type is LVCMOS (Low Voltage Complementary Metal-Oxide-Semiconductor).
