AFE7769EVM: AFE7769 Vs AFE7700

hi,

Comparing the two datasheets (AFE7769 Vs AFE7700), I do not find the technical difference but just the applications. TI explicitly says that the AFE7700 is for vector signal transceiver, which is exactly what I need to build a multiple-port VNA working at the frequency about several hundred MHz to 2 GHz). Could you help to list the main difference between the two?

I kind of prefer to use AFE7700EVM. But I cannot find many supporting documents from TI website. I only can find the user guide for AFE7700EVM so far.

I am planning to use either one with TSW14J57EVM (with Intel's Arria 10), which is the most suitable choice?

Best regards,
Felix

Hi Felix,

As given in the datasheet, AFE7700 supports RF input/output frequencies from 600MHz to >5GHz. 4 Tx channels support input BW of upto 600MHz and 4 Rx channels support BW of upto 200MHz. If these specifications are enough for your system, AFE7700 is suitable for this development.

Vijay
