Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Ensure that the 1.8V supply voltage aligns with your target circuit's power rails. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs. Check for any specific environmental operating temperature ranges required by your application to ensure reliable performance under all conditions.

Selection Notes

Select this oscillator when a 10.356 MHz reference signal is required with minimal power usage. The 1.8V supply makes it suitable for modern low-voltage digital circuits. Consider the 4-SMD package size if board real estate is limited. Ensure that the host system can support the standby control signal if power management is a priority. Verify that the output drive strength meets the capacitive load requirements of the connected components.
