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 dimensions fit within your PCB footprint constraints. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliable assembly.

Oscillators Selection Notes

Select this component when a precise 27.52 MHz reference is required with low power consumption capabilities. The LVCMOS output ensures compatibility with standard digital logic families. Consider the enable/disable feature if power management during idle states is critical. Verify that the operating temperature range meets your environmental specifications.

Oscillators Part Context

This part belongs to Mercury Electronics' series of standard crystal oscillators. The '18' prefix likely indicates the 1.8V supply voltage requirement, while 'QHTF' denotes the package type or series characteristics. The suffix '-OE' may indicate specific ordering or packaging options. Mercury Electronics specializes in frequency control products including quartz crystals and various oscillator types.

Oscillators Replacement Considerations

Direct replacements must match the 27.52 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical parameters such as phase noise and jitter if applicable.
