Other Parts Discussed in Thread: TRF7964A , TRF7970A Hi,
I'm working on a TRF7964A design and have a few questions:
SLOA205 says TRF79xx I/O is pulled down by 44-k resistors internally when it enters PDM. Does this include the TRF7964A? Is PDM the…
Regarding the interaction, I am planning to build an application in order to transfer data between two TRF7964A modules and also between one module and a smartphone. The transfer would include sending data stored on module to other device and receiving…
