Procurement Notes

Verify the specific suffix BQGI to confirm the CABGA-165 package type and industrial temperature rating. Ensure compatibility with 3.3V logic levels and check for moisture sensitivity handling requirements during assembly. Confirm that the 166 MHz speed grade meets the target system timing constraints before finalizing procurement decisions.

Selection Notes

Select this component when a wide 36-bit data path is required alongside high-frequency synchronous operation. It serves as a direct replacement for legacy IDT variants within the same family. Consider the 165-CABGA footprint for PCB layout planning. Verify that the system power supply can support the peak current draw specified in the datasheet under maximum load conditions.

FAQ

What is the difference between the S and SA suffixes in this series?

The SA suffix typically denotes the industrial temperature range (-40°C to +85°C) and specific packaging options like CABGA, whereas other suffixes may indicate commercial ranges or different packages.

Is this component compatible with 5V logic?

No, the 71V35761SA166BQGI is designed for 3.3V operation only. Using it with 5V logic will likely damage the device due to overvoltage on the I/O pins.
