Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 28.416 MHz operation. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the LVCMOS output level is compatible with the receiving logic inputs. Check that the 4-SMD package footprint fits the PCB layout constraints. Validate the enable/disable functionality requirements against the system power management scheme.

Oscillators Selection Notes

Select this model when a 28.416 MHz clock signal is specifically required. Consider the 1.8V operating voltage for compatibility with low-voltage logic families. The enable/disable feature is suitable for battery-operated or power-sensitive designs. The small 2.0x1.6 mm package aids in space-constrained layouts. Verify that LVCMOS output swing meets the noise margin requirements of the application.

Oscillators Part Context
