25QHTF21-176.840-PD

Oscillators Overview

The 25QHTF21-176.840-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 176.84 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 2.5V 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

• Supports low-voltage operation at 2.5V
• Integrates standby mode for power reduction
• Provides LVCMOS digital output signals
• Utilizes lead-free surface-mount packaging

Oscillators Applications

• High-speed data communication interfaces
• Network synchronization equipment
• Digital signal processing systems
• Test and measurement instrumentation

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 2.5V supply rail is stable within the operational limits defined in the official datasheet. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 176.84 MHz clock source is required for LVCMOS-compatible circuits. Consider the 2.5V operating voltage and standby capability if power efficiency is a priority. The small 2.0x1.6mm form factor makes it suitable for space-constrained designs requiring high-frequency performance without excessive board real estate.

Oscillators Part Context

This model belongs to the 25QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized package size. The 'PD' suffix indicates the inclusion of a power-down feature, distinguishing it from continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 176.84 MHz frequency, LVCMOS output, 2.5V supply, and 4-SMD 2.0x1.6mm package. Verify pin compatibility and thermal characteristics. Cross-reference with other manufacturers offering identical specifications to ensure functional equivalence.
