18QHTF21-86.663-PD

Overview

The 18QHTF21-86.663-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 86.663 MHz and utilizes LVCMOS output logic. The device is designed for surface mount applications in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. It functions on a 1.8V supply voltage and includes a standby or power-down control feature. The component supports an operating temperature range of -40°C to 85°C and offers a frequency stability of ±50ppm.

Feature Summary

• Supports low-voltage operation at 1.8V with LVCMOS output compatibility
• Features integrated standby and power-down control functionality
• Utilizes a compact 4-SMD no-lead surface mount package

Applications

• High-speed digital signal processing circuits
• Communication equipment requiring precise clock timing
• Portable electronic devices with space constraints

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout guidelines. Check for any specific handling instructions regarding the no-lead package during assembly.

Selection Notes

Select this component when a small form factor and low power consumption are critical. The LVCMOS interface ensures compatibility with standard logic families. Consider the ±50ppm stability for applications requiring moderate precision. The wide industrial temperature range makes it suitable for diverse environmental conditions.

Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics, which focuses on miniaturized oscillators. The series is characterized by its small 2.0x1.6mm footprint and low voltage operation. It serves as a timing source for various embedded systems and consumer electronics where size and power efficiency are prioritized over ultra-high stability.

Replacement Considerations

Direct substitutes may include other 1.8V LVCMOS oscillators in a 4-SMD 2.0x1.6mm package from Mercury Electronics or other manufacturers. Verify pinout compatibility and electrical specifications such as current consumption and drive strength. Cross-reference part numbers like 18QHTF21 variants with different frequencies if the exact 86.663 MHz is unavailable.
