Oscillators Procurement Notes

Verify the specific supply voltage requirement against the target circuit design, as this variant specifies 3.3V operation. Confirm that the 4-SMD no-lead package footprint matches the PCB layout constraints. Ensure the LVCMOS output levels are compatible with the receiving logic inputs to prevent signal integrity issues during operation.

Oscillators Selection Notes

Select this component when a 41.5 MHz reference signal is required with low-power standby functionality. Consider the 3.3V operating voltage constraint relative to other available variants. Evaluate the physical size requirements against the 2.0x1.6 mm package dimensions to ensure adequate board space allocation for the selected oscillator solution.
