Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs. Check for any specific operating temperature range limitations defined in the official datasheet for your application environment.

Oscillators Selection Notes

Select this component when a 36.864 MHz clock signal is required with low voltage operation. Consider the 2.0x1.6mm footprint if board space is limited. Evaluate the need for power-down capabilities to manage battery life in portable applications. Ensure the LVCMOS output is suitable for the target digital logic family. Compare against other Mercury Electronics models for alternative frequencies or package sizes if needed.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal oscillators. The series typically offers various frequencies and voltage options.
