It is housed in a compact 4-SMD, No Lead package with dimensions of 0.079" L x 0.063" W (2.00mm x 1.60mm) and a maximum seated height of 0.031" (0.80mm).

Oscillators Feature Summary

• Integrates a standby mode to reduce power consumption during inactive periods.
• Delivers stable clock signals via LVCMOS output interface.
• Utilizes a leadless surface-mount design for automated assembly compatibility.

Oscillators Applications

• General purpose digital circuit timing references
• Embedded systems requiring low-power standby capabilities
• Consumer electronics utilizing 2.5V logic levels

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Ensure the 2.5V supply voltage aligns with your target platform's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific reflow soldering profile recommendations provided in the official datasheet to ensure joint integrity.

Oscillators Selection Notes

Select this component when a precise 71.428571 MHz clock source is required with low power dissipation capabilities. The LVCMOS output is suitable for direct interfacing with standard digital logic families operating at 2.5V. Consider the small form factor for space-constrained designs. Evaluate the standby feature necessity if power management is a critical design constraint for the application environment.

Oscillators Part Context

This part belongs to the 25QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies within the XO category. The suffix PD indicates the inclusion of a power-down or standby pin functionality. This model represents a specific frequency variant within the broader family of surface-mount clock generators designed for modern electronic devices.

Oscillators Replacement Considerations

Cross-reference tools may identify parametrically similar parts. Verify that any substitute matches the 71.428571 MHz frequency, 2.5V supply, LVCMOS output, and 4-SMD package dimensions. Ensure the replacement also supports the standby function if required by the design.
