Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your 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. Check for any specific operating temperature range limitations defined in the official datasheet for your intended environment.

Oscillators Selection Notes

Select this component when a 30.4 MHz reference clock is required with LVCMOS compatibility. Consider the 1.8V supply constraint and the need for a power-down feature. Evaluate the 2.0x1.6mm package size against available board space. Compare performance metrics such as phase noise and stability if critical for your application against other available oscillator options.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a small SMD form factor. The 'PD' suffix indicates the inclusion of a power-down pin or function. Similar parts in this series include different frequency variants like 8.000 MHz or 51.200 MHz, sharing the same package and electrical characteristics.

Oscillators Replacement Considerations

Direct replacements must match the 30.4 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar low-profile oscillators with identical electrical specifications.
