18QHTF21-16.777216-OE

Oscillators Overview

The 18QHTF21-16.777216-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 16.777216 MHz and utilizes LVCMOS output logic levels. The component is designed for operation with a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• Supports enable and disable functionality for power management
• Utilizes LVCMOS output interface for digital compatibility
• Compact 4-SMD no-lead surface mount package design

Oscillators Applications

• Digital signal processing systems requiring precise clock timing
• Communication equipment utilizing standard frequency references
• Embedded systems operating on 1.8V power supplies

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure the correct frequency and package variant matches the design requirements. Confirm that the manufacturer designation aligns with Mercury Electronic Ind Co Ltd specifications. Cross-reference the part number against official distributor catalogs to validate authenticity and technical documentation availability before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The small 2.0x1.6mm footprint makes it suitable for space-constrained circuit boards. Ensure the application supports the enable/disable control feature if power efficiency during idle states is a priority for the system design.

Oscillators Part Context

This oscillator belongs to the QHTF series from Mercury Electronics, which focuses on high-frequency stability in miniature packages. The series is widely used in consumer electronics and industrial applications where reliable timing signals are critical. Mercury has established itself as a pioneer in quartz crystal manufacturing since 1973.

Oscillators Replacement Considerations

Direct substitutes include other 16.777216 MHz LVCMOS oscillators in 4-SMD 2.0x1.6mm packages from compatible manufacturers. Verify pinout compatibility and voltage tolerance before substitution. Alternative part numbers within the same family may offer different temperature ranges or load capacitance options.
