18QHTF21-40.965-PD

Oscillators Overview

The 18QHTF21-40.965-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 40.965 MHz and utilizes LVCMOS output logic levels. 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, suitable for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• LVCMOS output interface
• Integrated standby mode
• Surface-mount construction

Oscillators Applications

• General clock signal generation
• Digital system timing references
• Embedded controller synchronization

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD package footprint matches the PCB layout silkscreen and copper pad dimensions to guarantee proper soldering and mechanical stability during operation.

Oscillators Selection Notes

Select this component when a precise 40.965 MHz reference is required with low power consumption capabilities. The LVCMOS output ensures compatibility with standard digital logic families operating at 1.8V. Consider the physical size constraints of the 4-SMD package for dense board layouts. Evaluate the need for power-down functionality if battery life or thermal management is a critical design factor.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount oscillators. The series typically offers various frequency options within a standardized small outline package. Mercury Electronics specializes in quartz-based frequency control products, providing stable timing solutions for consumer and industrial electronics applications requiring reliable clock sources.

Oscillators Replacement Considerations

Direct substitutes must match the 40.965 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter specifications before cross-referencing with other manufacturers' offerings.
