Overview
The 18QHTF21-92.8571-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 92.8571 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a power-down standby function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component supports an operating temperature range suitable for commercial applications.
Feature Summary
- Integrates LVCMOS output interface for digital circuit compatibility
- Includes power-down standby mode to reduce consumption
- Utilizes surface-mount no-lead packaging for automated assembly
Applications
- Battery-powered portable electronic devices
- Digital signal processing systems
- Communication equipment requiring precise timing
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail stability meets the oscillator's operational specifications. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent soldering defects during assembly.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The compact 4-SMD form factor makes it suitable for space-constrained designs. Consider the power-down feature if system-level energy efficiency is a priority compared to continuously running oscillators.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-form-factor quartz crystal oscillators. The series typically offers various frequencies within a single package outline, allowing designers to maintain consistent board layouts while adjusting timing parameters across different product variants.
Replacement Considerations
Direct substitutes include other 18QHTF21 series parts from Mercury Electronics with identical 2.0x1.6mm packages and 1.8V LVCMOS outputs, such as the 18QHTF21-51.200-PD or 18QHTF21-93.200-OE, provided the frequency difference is acceptable for the application.
