Overview
The 18QHTF21-86.930-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 86.93 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package suitable for surface-mount applications.
Feature Summary
- Supports active enable and disable control via input pin
- Generates stable clock signals using LVCMOS logic levels
- Designed for low-profile surface-mount integration
Applications
- Digital signal processing systems requiring precise timing
- Communication equipment utilizing standard clock frequencies
- Embedded systems with limited board space constraints
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply rail matches your system's power architecture. Ensure the enable pin logic levels are compatible with your controlling microcontroller or FPGA to prevent unintended oscillation states during operation.
Selection Notes
Choose this component when a fixed 86.93 MHz frequency is required with low-voltage operation. Consider the 4-SMD package size for space-constrained designs. Evaluate the need for enable/disable functionality to manage power consumption in standby modes compared to always-on alternatives.
Part Context
This oscillator belongs to the standard XO series from Mercury Electronics, focusing on quartz-based frequency stability. The manufacturer specializes in Taiwan-based quartz crystal production, offering reliable timing solutions for industrial and commercial electronics markets with established manufacturing history.
Replacement Considerations
Direct substitutes must match the 86.93 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and enable pin functionality. Cross-reference with other Mercury Electronics models in the same series for potential drop-in replacements if available.
