18QHTF21-30.240-PD

Oscillators Overview

The 18QHTF21-30.240-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 30.24 MHz and utilizes LVCMOS output logic. The device is designed for 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 with dimensions of 2.0 x 1.6 mm. This component serves as a precise clock source for digital circuits requiring low-power operation and small form factors.

Oscillators Feature Summary

• Integrates LVCMOS output logic for direct interface with digital systems
• Supports standby mode to reduce power consumption during idle periods
• Utilizes a leadless surface-mount package for automated assembly

Oscillators Applications

• Portable electronic devices requiring low power consumption
• Communication modules utilizing LVCMOS interfaces
• Embedded systems needing precise timing references

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD no-lead package specifications to prevent mounting issues during assembly.

Oscillators Selection Notes

Select this model when a 30.24 MHz clock signal is required with minimal power usage. The LVCMOS output is suitable for standard logic families operating at 1.8V. Consider the physical size constraints of the application, as the 2.0x1.6mm package is among the smaller options available for this frequency range.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-profile crystal oscillators. The series typically offers various frequencies within the same compact footprint, allowing designers to maintain consistent board layouts across different product variants while adjusting only the frequency parameter.

Oscillators Replacement Considerations

Direct substitutes include other 30.24 MHz LVCMOS oscillators in 2.0x1.6mm packages from manufacturers such as Epson or Nihon Dempa Kogyo. Verify pin compatibility and voltage levels when cross-referencing with alternative brands.
