Overview
The 18QHTF21-92.500-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 92.5 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is suitable for applications requiring precise timing signals within portable and space-constrained electronic systems.
Feature Summary
- Integrates LVCMOS output logic for direct interfacing with digital circuits
- Includes hardware enable/disable functionality for power management
- Utilizes a lead-free SMD package optimized for surface-mount assembly
Applications
- Portable consumer electronics requiring low-power clock sources
- Embedded systems needing precise timing synchronization
- Communication modules utilizing standard digital interfaces
Procurement Notes
Verify the specific suffix 'OE' to confirm the enable/disable feature and 1.8V operating voltage. Ensure the 4-SMD no-lead footprint matches the target PCB design. Cross-reference the 92.5 MHz frequency requirement against system specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration.
Selection Notes
Select this model when a 1.8V supply voltage is mandatory for the circuit design. Consider the enable/disable pin if dynamic power saving is required. Evaluate the 2.0x1.6mm package size against available board real estate. Compare performance against other Mercury series oscillators if different voltage levels or output types are needed.
Part Context
This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount crystal oscillators. The series provides various frequencies and voltage options. The '18' prefix typically indicates the 1.8V supply variant. The 'OE' suffix denotes the inclusion of an output enable control signal, distinguishing it from continuously running variants.
Replacement Considerations
Direct substitutes include the 18QHTF21-92.500-PD, which shares the same frequency and package but may differ in operational mode or suffix designation. Verify electrical compatibility before substitution.
