18QHTF21-38.864-PD

Oscillators Overview

The 18QHTF21-38.864-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 38.864 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down mode capability. It is housed in a compact 4-SMD, no lead package suitable for surface-mount applications.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby functionality to reduce power consumption during idle states
• Utilizes quartz-based technology for stable frequency generation

Oscillators Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific ordering suffix and frequency tolerance requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD no lead package dimensions fit the intended PCB footprint. Check availability status as distribution channels may vary.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The choice depends on the need for a standard XO configuration with standby capabilities. Consider the physical size constraints imposed by the 4-SMD package. Verify that the 38.864 MHz frequency meets the specific timing requirements of the application.

Oscillators Part Context

This part belongs to the Mercury Electronics Ind. Co. Ltd oscillator series, which includes various frequencies such as 50.0035 MHz and 6.000 MHz. These components share similar packaging and electrical characteristics but differ in nominal frequency. The manufacturer has a history of producing quartz crystals and oscillators since 1973.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts from Mercury Electronics with matching voltage and package specifications, such as 18QHTF21-50.0035-PD or 18QHTF21-6.000-PD, provided the frequency difference is acceptable for the application.
