Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to ensure correct package and temperature grade specifications. Confirm that the 81-CSBGA footprint matches the target PCB design. Check for any recent product change notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a single-clock solution with multiple output formats is required for high-speed serial interfaces. Ensure the input source matches the supported CMOS, TTL, or crystal options. Verify that the 750MHz maximum frequency meets the system's jitter and bandwidth requirements for Ethernet or SONET/SDH protocols.

Part Context

This part belongs to the MAX243xx series of clock synthesizers from Microchip Technology. These devices are engineered to provide precise clock generation and distribution for telecommunications and data communication equipment. The CSBGA package allows for compact integration into dense board layouts typical of modern networking hardware.

Replacement Considerations

Consult Microchip's official cross-reference tools for verified pin-compatible alternatives. Ensure any substitute maintains the same 81-CSBGA package and electrical characteristics for direct replacement.
