18QHTF21-24.734-PD

Oscillators Overview

The 18QHTF21-24.734-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 24.734 MHz with an LVCMOS output signal. 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 with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Features LVCMOS output compatibility
• Includes standby and power-down functionality

Oscillators Applications

• Portable electronic devices requiring low power consumption
• Communication systems utilizing standard clock signals
• Embedded controllers needing precise timing references

Oscillators Procurement Notes

Verify the specific suffix 'PD' indicates the power-down feature as documented. Confirm the 2.0x1.6mm package footprint matches your PCB layout requirements. Ensure the 1.8V supply rail is stable within the specified operating range to maintain frequency accuracy during standby transitions.

Oscillators Selection Notes

Select this component when a small form factor is required alongside low voltage operation. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the power-down capability if system-level energy efficiency is a priority compared to continuous oscillation models.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and package sizes, with the 2.0x1.6mm variant providing a balance between size and performance for space-constrained applications.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical pinout and electrical characteristics but different frequencies, such as 18QHTF21-24.000-PD. Cross-reference with other manufacturers offering 2.0x1.6mm LVCMOS XO packages only if pin compatibility and voltage levels are verified.
