Part Number: CC2630
Hello Team,
We need your help on our customer's concern below. Here is the question below.
We have a question regarding using different suppliers of a 32,768kHz crystal in an existed design for CC2630. As we are willing to extend the suppliers list for the 32.768kHz crystal..
We wanted to ask you kindly to support us with your opinion based on your experience on whether the second source crystals are suitable to be used for CC2630 ZigBee or not. The crystal comparison sheet will be listed as follows:

Furthermore, We were checking the specification of the CC2630 if the alternative crystals are a good fit. Luckily the alternatives seem within TI requirements as was mentioned in the datasheet.
Thank you so much in advance.
Best regards,
