Procurement Notes

Verify RoHS compliance status and specific packaging configuration prior to ordering. Confirm current availability as stock levels may vary by distributor. Ensure the selected variant matches the required pinout and thermal characteristics for the target PCB design. Check for any recent product change notifications or lifecycle updates directly from the manufacturer.

Selection Notes

Select this component when designing for dedicated marine VHF environments requiring integrated baseband processing. Consider the 48-VQFN package dimensions for layout constraints. Evaluate the 3V to 3.6V supply requirements against the system power architecture. Verify that the operating temperature range meets the environmental conditions of the intended deployment location.

Part Context

This part belongs to the CMX885/EV8850 series manufactured by CML Microcircuits. It serves as a specialized RF wireless miscellaneous IC focused on maritime communications. The Q3 suffix indicates the specific package type and material composition compared to other variants in the family.

Replacement Considerations

CMX885L4 is a direct alternative within the same series, offering identical functionality but utilizing a 48-LQFP(7x7) package instead of the VQFN form factor.
