and to stabilize the regulator.
DC power supply decoupling point for IF,
Demodulator, and Data Slicer circuits. A
capacitor must be tied between this pin
and ground to decouple (bypass) noise
and to stabilize the regulator.
DC power supply input to the interface
logic and control registers. This supply is
not connected internally to any other
supply pin, but its voltage must be less
than or equal to the VCC5 supply and
greater than 2.7 V. A capacitor must be
tied between this pin and ground to
decouple (bypass) noise.
Receive RF Input. Nominal impedance at
902 to 928 MHz is 17-50j
matching network required for optimum
noise figure. This input is to the base of
an NPN transistor and should be AC
coupled.
