18QHTF21-63.360-PD

Overview

The 18QHTF21-63.360-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 63.36 MHz with LVCMOS output logic. The device requires a 1.8V supply voltage and features a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package suitable for surface mount applications.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby and power-down functionality
• Utilizes LVCMOS output logic levels

Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded microcontroller timing sources

Procurement Notes

Verify the specific frequency suffix matches system requirements. Confirm the 1.8V supply compatibility with target circuitry. Ensure the 4-SMD no-lead package footprint aligns with PCB layout specifications. Check for RoHS compliance status if required by project standards.

Selection Notes

Choose this component when a precise 63.36 MHz reference is needed with low power consumption. The LVCMOS interface ensures compatibility with standard digital logic families. The integrated power-down feature aids in battery-operated designs requiring extended standby times.

Part Context

Mercury Electronics specializes in frequency control products, leveraging decades of experience in quartz crystal manufacturing. This model belongs to their series of surface-mount oscillators designed for reliable timing in modern electronic assemblies.

Replacement Considerations

Direct substitutes must match the 63.36 MHz frequency, 1.8V supply, and LVCMOS output. Verify pinout compatibility for the 4-SMD package. Cross-reference with other manufacturers offering similar small-form-factor oscillators.
