18QHTF21-25.125-PD

Oscillators Overview

The 18QHTF21-25.125-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 25.125 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports standby mode for power reduction
• Utilizes LVCMOS output interface
• Compact surface-mount form factor

Oscillators Applications

• General clock signal generation
• Digital circuit timing reference
• Embedded system synchronization

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required voltage levels and output types. Confirm that the 4-SMD no-lead package matches the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly before placing orders.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a small footprint. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the power-down capability if system-level energy efficiency is a priority during idle periods.

Oscillators Part Context

This model belongs to the QHTF series of quartz crystal oscillators from Mercury Electronics. The series offers various frequencies and voltages within a standardized small outline package. The 'PD' suffix typically indicates the inclusion of a power-down control feature for enhanced power management capabilities.

Oscillators Replacement Considerations

Direct substitutes include other 25.125 MHz LVCMOS oscillators in a 2.0x1.6mm SMD package with 1.8V operation. Verify pinout compatibility and electrical specifications before swapping. Cross-reference with similar Mercury part numbers such as those in the same QHTF family.
