Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD footprint matches the PCB layout design. Check the operating temperature range suitability for the intended environment. Validate the LVCMOS output swing levels with downstream components.

Selection Notes

Select this component when a 75.33 MHz clock source is required with low voltage operation. Consider the 4-SMD package size for space-constrained designs. Evaluate the 26mA current consumption against power budget constraints. Ensure the -40°C to 85°C temperature range meets environmental specifications. Verify compatibility with LVCMOS logic families used in the application.
