18QHTF21-24.800-PD

Oscillators Overview

The 18QHTF21-24.800-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 24.8 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down function to reduce consumption during inactive periods. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V with LVCMOS output compatibility
• Includes standby and power-down functionality for energy efficiency
• Utilizes a compact 4-SMD no-lead surface-mount package

Oscillators Applications

• Digital signal processing systems requiring stable clock sources
• Communication equipment utilizing LVCMOS interfaces
• Portable electronic devices where low power consumption is critical

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target circuit's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific environmental operating temperature ranges required for your application environment.

Oscillators Selection Notes

Select this component when a 24.8 MHz clock signal is required with LVCMOS output levels. Consider the 1.8V operating voltage and the availability of a power-down feature for power-sensitive designs. Evaluate the 2.0x1.6 mm package size against available board space. Compare performance against other oscillators if higher frequencies or different logic families are needed.

Oscillators 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 feature, distinguishing it from standard continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 24.8 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical specifications such as jitter and phase noise. Consult manufacturer cross-reference lists for equivalent parts from other suppliers.
