Overview
The 18QHTF21-86.980-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a nominal frequency of 86.98 MHz and utilizes LVCMOS output logic levels. The device is designed for a supply voltage of 1.8V and includes enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. This component serves as a precise clock source for digital circuits requiring stable frequency generation.
Feature Summary
- LVCMOS output interface for direct logic integration
- Integrated enable/disable control pin for power optimization
- Compact surface-mount footprint suitable for space-constrained designs
Applications
- Digital signal processing systems
- Communication equipment clocking
- Embedded system timing references
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required voltage and load conditions. Confirm that the OE suffix aligns with the intended enable functionality and packaging style before finalizing procurement orders to avoid mismatched specifications.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. Ensure the application can accommodate the 2.0x1.6 mm package size and that the 86.98 MHz frequency matches the system clock requirements without additional dividers or multipliers.
Part Context
This part belongs to the H_QF series of differential oscillators from Mercury Electronics, although configured here as a single-ended XO. The manufacturer specializes in quartz frequency control products, leveraging decades of expertise in crystal manufacturing to provide reliable timing solutions for industrial and consumer electronics.
Replacement Considerations
Direct substitutes must match the 86.98 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics before swapping with other manufacturers' offerings to ensure circuit integrity.
