Procurement Notes

Verify the specific suffix LDG1 against BLDG1 to ensure correct pinout and electrical characteristics match your design requirements. Confirm that the VQFN-64 package dimensions align with your PCB footprint constraints. Check current availability status as supply levels may fluctuate. Ensure your board design accommodates the specified thermal dissipation for the operating temperature range.

Selection Notes

Select this component when designing systems requiring precise clock synchronization across multiple outputs. It is appropriate for applications needing dual-channel input processing with high-frequency output capabilities. Consider the 1.8V and 3.3V voltage compatibility for mixed-signal environments. Evaluate the 750 MHz maximum output frequency against your system's bandwidth needs.
