RF Receivers Procurement Notes

Verify the specific suffix 'BDTR' indicates the tape-and-reel packaging configuration and includes the Controller Area Network interface variant. Confirm that the ordering quantity aligns with the standard factory pack quantity of 4,000 units. Ensure compatibility with the required supply voltages, specifically the 1.08V to 1.32V digital core range. Check for RoHS3 compliance status if environmental regulations are critical for the target market.

RF Receivers Selection Notes

Select this component when a small footprint and low bill of materials are required for multi-constellation positioning. The integrated design eliminates external passive components typically needed for RF circuits. Consider the 99-TFBGA package size for space-constrained PCB layouts. Evaluate the need for CAN interface support if automotive or industrial communication protocols are necessary for the application.

RF Receivers Part Context
