Procurement Notes

Verify the exact operating temperature range and load capacitance requirements against your specific circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a 76.2805 MHz frequency is required with LVCMOS outputs. Consider the 1.8V supply constraint and enable/disable feature for power-sensitive designs. Compare package dimensions against available board space. Evaluate thermal performance within the specified operating temperature range to ensure reliability under intended environmental conditions.

Part Context

Mercury Electronics Ind. Co. Ltd specializes in frequency-control products including quartz crystals and oscillators. This model belongs to their standard XO series, offering reliable timing solutions. The company has decades of experience in Taiwan's quartz industry, providing components for various industrial and consumer electronics applications requiring accurate clock signals.

Replacement Considerations

The 18QHTF21-76.2805-PD offers similar specifications but features standby (power down) functionality instead of simple enable/disable.
