Oscillators Overview

The 18QHTF21-3.570-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 3.57 MHz and utilizes an LVCMOS output signal format. The device requires a supply voltage of 1.8V and features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. The component ensures frequency stability of ±50ppm and supports an operating temperature range from -40°C to 85°C.

Oscillators Feature Summary

• Supports LVCMOS output signal format for digital interface compatibility
• Includes enable/disable functionality for efficient power management
• Provides stable frequency generation within specified temperature ranges

Oscillators Applications

• General purpose timing circuits requiring precise clock signals
• Embedded systems utilizing low-voltage logic interfaces
• Consumer electronics devices with space-constrained PCB layouts

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure that the 1.8V supply voltage aligns with the system power rails. Confirm that the enable/disable pin configuration matches the control logic levels used in the application. Check the package footprint dimensions to ensure compatibility with the printed circuit board layout and soldering processes.

Oscillators Selection Notes

Select this component when a small form factor oscillator is required for low-voltage applications. Consider the ±50ppm stability specification to ensure it meets the timing accuracy needs of the system. Evaluate the thermal performance within the -40°C to 85°C range to guarantee reliable operation under expected environmental conditions. Compare alternative frequencies if the exact 3.57 MHz rate is not strictly necessary for the design.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators produced by Mercury Electronic Ind. Co., Ltd. The series is characterized by its compact 4-SMD no-lead package and support for various standard frequencies. Mercury Electronics is a established supplier of frequency control products, including quartz crystals and oscillators, with a focus on providing reliable timing solutions for electronic equipment.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with different frequencies, such as 18QHTF21-3.996-OE or 18QHTF21-9.465-OE, provided the frequency difference is acceptable. Cross-referencing with other manufacturers' 3.57 MHz LVCMOS oscillators in similar packages may be possible but requires careful verification of electrical parameters and pinout compatibility.
