Part Number: TRF7970A
Is the more information on RX_IN1/RX_IN2 requirements when the Regulator and I/O Control Register (0x0B) bit 6 (en_ext_pa) is set, enabling input from an external demodulator? I don't see any spec's, such as voltage levels, logic threshold, pulse width, etc -- things one would normally look for on a digital interface. Further, there's no information on side effects of enabling bit 6, e.g. I assume register 0x0A is don't care.
I'll appreciate anything you can point me to.
