18QHTF21-65.100-PD

Overview

The 18QHTF21-65.100-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 65.1 MHz and utilizes 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 with dimensions of 2.0x1.6 mm. This component is designed for applications requiring precise timing signals within low-power constraints.

Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Includes a standby or power-down mode to reduce operational current consumption
• Utilizes a small form factor 4-SMD no lead surface mount package

Applications

• General purpose clock signal generation in electronic circuits
• Timing reference sources for digital systems requiring 1.8V operation
• Portable devices utilizing low-power oscillator solutions

Procurement Notes

Verify the specific ordering suffix and frequency tolerance against the official Mercury Electronics datasheet before procurement. Confirm that the 1.8V supply requirement aligns with your system design. Ensure the 4-SMD package footprint matches your PCB layout specifications. Request the latest manufacturing documentation to confirm compliance with current industry standards.

Selection Notes

Select this component when a 65.1 MHz clock source is required with LVCMOS outputs. Consider the 1.8V operating voltage and standby functionality for power-sensitive designs. Evaluate the 2.0x1.6 mm package size against available board space. Compare performance metrics such as phase noise and stability if specified in the manufacturer's technical data.

Part Context

This part belongs to the Mercury Electronics XO series, which manufactures quartz crystals and oscillators. The company has a history of producing frequency control products including TCXOs and VCXOs. The 18QHTF21 model represents a standard oscillator variant designed for general timing applications in consumer and industrial electronics.

Replacement Considerations

Consult the official Mercury Electronics substitution guide for verified alternatives. Cross-reference pinouts and electrical characteristics with potential substitutes. Verify that any replacement maintains the 1.8V supply and LVCMOS output requirements. Do not assume interchangeability without checking the manufacturer's official documentation.
