Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no lead package footprint matches your PCB layout constraints to avoid assembly issues.

Selection Notes

Select this model when a standard XO with LVCMOS outputs is required at 82.62 MHz. Consider the 1.8V operating voltage and the availability of a power-down feature for battery-operated applications. Evaluate the 2.0x1.6mm package size against space limitations in the target design compared to other available oscillator packages.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a small SMD package. The manufacturer specializes in quartz crystals and oscillators, providing timing solutions for diverse electronic applications. The PD suffix indicates the inclusion of a power-down capability within the device functionality.

Replacement Considerations

Direct replacements must match the 82.62 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no lead package. Verify pinout compatibility and electrical specifications such as phase noise and jitter if critical performance is required.
