The device is designed for 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. This component is engineered for applications requiring precise clock signals within a small form factor.

Feature Summary

• Supports standby mode for power reduction
• Compact surface-mount package design
• LVCMOS output compatibility

Applications

• General digital clock generation
• Embedded system timing references
• Communication interface synchronization

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD no-lead package specifications to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Choose this model when a low-voltage 1.8V operation is required alongside a specific 104.254 MHz frequency. The LVCMOS output ensures compatibility with standard digital logic families. Consider the physical size constraints of your design, as the 2.0x1.6mm package is suitable for space-sensitive applications. Verify thermal operating range requirements if used in extreme environments.

Part Context

This part belongs to the QHTF series from Mercury Electronics, which focuses on high-frequency oscillators in small packages. The 'PD' suffix indicates the inclusion of a power-down feature. Mercury Electronics has extensive experience in quartz crystal manufacturing, providing reliable frequency control solutions for various electronic industries globally.

Replacement Considerations

Direct substitutes must match the 104.254 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Check datasheets for equivalent parts from other manufacturers offering identical electrical characteristics and pinout configurations to ensure seamless integration without redesign.
