18QHTF21-58.372-PD

Overview

The 18QHTF21-58.372-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 58.372 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features a power-down standby function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V for energy efficiency
• Includes a power-down standby mode to reduce consumption
• Utilizes LVCMOS output logic for digital interface compatibility

Applications

• Battery-powered portable devices
• Compact electronic systems requiring precise timing
• Low-power digital circuit clock generation

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply rail stability meets the oscillator's operational specifications. Ensure the PCB layout accommodates the 2.0x1.6mm SMD footprint without interference from adjacent components.

Selection Notes

Select this component when a small form factor and low voltage operation are critical constraints. The integrated power-down feature makes it suitable for applications requiring active and inactive states. Compare performance metrics against alternative oscillators if higher frequencies or different logic levels are needed.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various standard frequencies and supports low-voltage operations. The 'PD' suffix indicates the inclusion of a power-down control pin for standby functionality.

Replacement Considerations

Direct substitutes include other 18QHTF21 variants with compatible frequencies such as 18QHTF21-6.562-PD or 18QHTF21-51.200-PD, provided the frequency difference is acceptable for the system design.
