18QHTF21-25.100-PD

Oscillators Overview

The 18QHTF21-25.100-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 25.1 MHz and utilizes LVCMOS output logic. 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 2.0mm x 1.6mm.

Oscillators Feature Summary

• LVCMOS output logic interface
• Integrated standby and power-down functionality
• Compact 4-SMD no lead surface mount package

Oscillators Applications

• General purpose timing circuits
• Digital signal processing systems
• Communication equipment

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD footprint matches the PCB layout design to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The small 2.0x1.6mm package makes it suitable for space-constrained designs. Consider the power-down feature if system-level power efficiency is a priority. Validate frequency accuracy specifications against the application's clock tolerance requirements.

Oscillators Part Context

This part belongs to the QHTF series of quartz crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage levels. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from continuous-operation variants within the same physical package family.

Oscillators Replacement Considerations

Direct substitutes must match the 25.1 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter before swapping manufacturers.
