Overview
The 18QHTF21-80.5308-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co. Ltd. It operates at a frequency of 80.5308 MHz and utilizes LVCMOS output logic levels. The device supports an enable/disable control function via the supply voltage, which is specified as 1.8V. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.
Feature Summary
- Supports LVCMOS output interface
- Features enable/disable control functionality
- Utilizes 1.8V supply voltage operation
Applications
- General electronic timing circuits
- Embedded systems requiring clock signals
- Consumer electronics devices
Procurement Notes
Verify the specific suffix 'OE' against the manufacturer's current datasheet to confirm the enable/disable pin configuration matches your design requirements. Ensure the 1.8V operating voltage aligns with your system power rails. Confirm the 4-SMD no-lead footprint dimensions with your PCB layout guidelines before finalizing component selection.
Selection Notes
Select this component when a low-voltage 1.8V oscillator with digital enable capabilities is required. The LVCMOS output ensures compatibility with standard logic families. Consider the 4-SMD package size for space-constrained designs. Verify that the 80.5308 MHz frequency meets the specific timing needs of the target application circuit.
Part Context
This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronic. The series typically offers various frequencies and supply voltages. The 'OE' suffix indicates specific operational characteristics, likely related to the enable/disable feature, distinguishing it from other variants like 'PD' (Power Down) or unmarked versions within the same package family.
Replacement Considerations
Direct substitutes include other 18QHTF21 series parts with identical 80.5308 MHz frequency, 1.8V supply, and LVCMOS output. Check for compatible packages such as 4-SMD No Lead. Ensure any replacement maintains the enable/disable functionality if critical to the system design.
