Oscillators 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 platform'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.

Oscillators Selection Notes

Select this model when a 22.008 MHz clock signal is specifically required for system synchronization. Consider the 1.8V supply constraint and LVCMOS interface compatibility with your microcontroller or FPGA. The small 2.0x1.6mm footprint makes it suitable for dense PCB layouts. Evaluate the need for power-down capabilities if battery life or thermal management is a critical design factor for the end product.
