18QHTF21-3.6567-OE

Oscillators Overview

The 18QHTF21-3.6567-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 3.6567 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features an enable/disable function for power management. Frequency stability is specified at ±50ppm, and it supports an operating temperature range from -40°C to +85°C. The component is housed in a compact 4-SMD, No Lead package.

Oscillators Feature Summary

• Integrates enable/disable functionality for dynamic power control
• Delivers LVCMOS output signals compatible with standard digital interfaces
• Maintains frequency stability within ±50ppm tolerance

Oscillators Applications

• General purpose clock generation in embedded systems
• Timing reference for low-frequency digital circuits
• Portable electronic devices requiring low power consumption

Oscillators Procurement Notes

Verify the specific frequency value matches the system requirement of 3.6567 MHz. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the LVCMOS output compatibility is suitable for the connected logic family. Check that the ±50ppm stability meets the timing accuracy needs of the application.

Oscillators Selection Notes

Select this component when a precise 3.6567 MHz clock source is required with low power operation. The 1.8V supply makes it suitable for battery-powered or low-voltage designs. The enable/disable feature allows for additional power savings during idle periods. Consider the ±50ppm stability if tight timing synchronization is not critical.

Oscillators Part Context

This model belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and supply voltages, including 1.8V and 3.3V options. These oscillators are designed for applications requiring reliable timing with minimal footprint and power consumption.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical pinout and electrical characteristics but different frequencies. Cross-referencing with similar LVCMOS oscillators from other manufacturers requires verifying supply voltage, output logic, and package dimensions.
