I anm forwarding a question from my customer for the TRF3705:
>>>> I plan to use TRF3705 modulator chip for our RF transceiver. However, I have some questions:
Pin 1 is to power the chip on and off. If I want to keep the chip on all the time, is it OK to leave it open (NC)?
Pin 6 is to adjust for high gain. If I want it to have high gain all the time, is it OK to pull it up to 3.3V ? >>>>
in the d/s there are digital input specs for the PD pin, but not for the GC pin.
Regards, George Biner, Arrow LA
Yes, you can leave PD pin open it is internally pulled down and GC pin can be pull to 3.3V.
