25QHTF57-10.900-PD

Oscillators Overview

The 25QHTF57-10.900-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a fixed frequency of 10.9 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 2.5V and features a power-down function to reduce consumption when not in use. It is housed in a compact 4-SMD, No Lead package with dimensions of 5.0mm x 3.2mm.

Oscillators Feature Summary

• Supports low-voltage operation at 2.5V
• Includes standby mode via power-down control
• Provides standard LVCMOS signal output

Oscillators Applications

• General clock generation for digital circuits
• Timing reference for communication interfaces
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 10.9 MHz specification. Confirm that the 2.5V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint corresponds to the PCB layout requirements. Check for any specific operating temperature range constraints defined in the official datasheet before finalizing the order.

Oscillators Selection Notes

Select this component when a precise 10.9 MHz timing source is required for low-power applications. The choice depends on the necessity for LVCMOS compatibility and the availability of a 2.5V power rail. Consider the physical size constraints imposed by the 5.0x3.2mm package. Evaluate if the power-down feature is necessary for energy management in the final product design.

Oscillators Part Context

This part belongs to the 25QHTF57 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within a small form factor. The 'PD' suffix indicates the inclusion of a power-down pin for active control. This model specifically targets applications requiring stable clock signals in space-constrained environments.

Oscillators Replacement Considerations

Direct substitutes include other 10.9 MHz XO models from Mercury Electronics with identical pinouts and electrical characteristics. Cross-reference with similar 4-SMD packages from other manufacturers only if pin-compatible and electrically equivalent specifications are confirmed.
