Overview
The 18QHTF21-86.613-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 86.613 MHz and utilizes LVCMOS output logic. The device is powered by a single 1.8V supply voltage and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component is designed for surface-mount assembly and supports standard operating temperature ranges typical for commercial electronic applications.
Feature Summary
- LVCMOS output logic interface
- Integrated enable/disable control pin
- Compact 4-SMD no-lead surface mount package
- Standard crystal oscillator configuration
Applications
- General purpose clock generation in embedded systems
- Digital signal processing circuits requiring precise timing
- Communication modules utilizing standard frequency references
- Consumer electronics with space-constrained PCB layouts
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB silkscreen and copper pad layout to prevent assembly errors. Check for any specific handling instructions regarding electrostatic discharge protection during storage and installation.
Selection Notes
Select this component when a low-profile surface-mount oscillator is required for 86.613 MHz applications. The LVCMOS output is suitable for direct interfacing with digital logic families operating at 1.8V. Consider the enable/disable feature if power conservation is critical. Verify that the 2.0x1.6mm package size fits within the available board area constraints compared to larger oscillator packages.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a small SMD form factor. The series is designed for cost-effective mass production in consumer and industrial electronics. Mercury Electronics is a established manufacturer of quartz frequency control products, providing standardized solutions for timing needs across multiple industries.
Replacement Considerations
Direct replacements must match the 86.613 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Cross-referencing with other manufacturers' similar series may require verification of pinout compatibility and electrical specifications. Ensure substitute parts support the same enable/disable functionality if utilized in the original design.
