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 if used in extreme environments. Validate the power-down pin configuration with your control logic.

Oscillators Selection Notes

Select this oscillator when a 2.72 MHz clock signal is required with LVCMOS output compatibility. Consider the 1.8V supply voltage requirement for power budget calculations. The small 2.0x1.6 mm package is suitable for space-constrained designs. Evaluate the need for power-down functionality to manage standby current consumption. Compare performance metrics such as phase noise and stability against other available options if critical timing precision is needed.
