18QHTF21-63.328-PD

Overview

The 18QHTF21-63.328-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 63.328 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Integrates LVCMOS output logic for digital circuit compatibility
• Supports standby mode to reduce power consumption during idle periods
• Utilizes a leadless SMD package for automated surface-mount assembly

Applications

• General clock signal generation for embedded systems
• Timing reference for digital communication interfaces
• Power management circuits requiring low-power oscillation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct voltage and output specifications. Confirm that the leadless package type matches the PCB footprint requirements. Cross-reference the part number with the latest datasheet to validate operational temperature ranges and electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a 1.8V supply voltage is required alongside LVCMOS outputs. Ensure the design accommodates the 4-SMD no-lead form factor. Consider the standby feature if power efficiency is critical. Verify that the 63.328 MHz frequency aligns with the target system's clocking architecture and jitter requirements.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-voltage surface-mount solutions. The series typically offers various frequencies within a standardized package profile. This specific model provides a fixed frequency option for designs needing stable timing without external tuning components.

Replacement Considerations

Consult the manufacturer's cross-reference guide for direct substitutes. Ensure any replacement maintains the 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify frequency stability and operating temperature range compatibility with the original specification.
