Justification for other part numbers than CC8531????
I'm curious about your part numbering policy.
With CC8531, you can realize any configuration that you can set up using the Purepath Wireless Configuration?
Will TI manufacture any other part number in the future?
Why would that happen?
Hi,Currently there are 4 part numbers in the Purepath Wireless family, CC8520, CC8521, CC8530 and CC8531. The two first (CC852x) support 2 audio channels while the two latter (CC853x) support 4 audio channels. The devices ending with "1" has USB interface while the others have I2S interface.
Does this answer your question?

actually not since my question is:
Why do you have so many part numbers when just one i.e. CC8531 can cater everybody?
Why don't you concentrate your efforts to one part only? Your evalaluation kits are with CC8531 only .... ???
Is there really a manufacturing cost difference between different versions?
Bottom line is yes and in the consumer space our end customers do not want to to pay additional cost for features they do not use.
For the development kits we provide them with CC8531 to ease our own manufacturing and allow customer to have fewer kit to choose from.Hope that answers your question.
Best regards, Kjetil

can you confirm that the performance of CC852X and CC853X chips are the same when transmitting PCM stereo signal?
So you did not do any improvements in the radio performance etc. (other than adding more channels and the third PCM channel that we should not use?).
Yes I can confirm that the RF performance for these devices are the same. If you are transmitting a stereo PCM signal then there is absolutely no need to use the CC853x chips.
