18QHTF21-24.5153-PD

Oscillators Overview

The 18QHTF21-24.5153-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 24.5153 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby power-down mode to reduce energy consumption during inactive periods. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, suitable for space-constrained electronic designs requiring precise timing signals.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V with LVCMOS output compatibility
• Includes a dedicated standby or power-down function for energy efficiency
• Utilizes a small-footprint 4-SMD no-lead surface-mount package

Oscillators Applications

• Digital signal processing circuits requiring stable clock sources
• Embedded systems utilizing low-voltage microcontrollers
• Portable consumer electronics with strict size constraints

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply rail is stable within the operational limits specified in the official datasheet. Ensure the PCB footprint matches the 2.0x1.6 mm SMD package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 24.5153 MHz reference is required for LVCMOS-compatible digital interfaces. Consider the 1.8V operating voltage and standby capability if power management is critical. The small 4-SMD form factor makes it appropriate for high-density board layouts where larger packages cannot fit. Evaluate thermal performance and frequency stability needs relative to the application environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various standard frequencies with consistent electrical characteristics and packaging. The 'PD' suffix indicates the inclusion of a power-down control feature, distinguishing it from continuous-operation variants within the same physical package family.

Oscillators Replacement Considerations

Direct substitutes must match the 24.5153 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical parameters such as phase noise and jitter before swapping manufacturers.
