Description
Non-inverting input of the I channel A/D converter, to be connected to I out
of the RF2722. Analog input.
Inverting input of the I channel A/D converter, to be connected to IB out of
the RF2722. Analog input.
Inverting input of the Q channel A/D converter, to be connected to QB out
of the RF2722. Analog input.
Non-inverting input of the Q channel A/D converter, to be connected to Q
out of the RF2722. Analog input.
Transmit start. A rising edge on this signal initiates the transmit sequence
(PA ramp up). A falling edge on this signal begins the transmit shut down
sequence (PA ramp down). Digital input with weak pulldown.
General purpose output 1. This pin can be used to control a T/R switch.
General purpose digital output (GPO).
General purpose output 2. This pin can be used to control a T/R switch.
General purpose digital output (GPO).
Digital Receiver, ADC, and DAC voltage regulator output. A decoupling
capacitor is required to ground. DC output voltage of 2.5V when the
receive circuits are enabled.
Receive power supply. Supply filtering components may be required in
some applications (e.g. series resistor and shunt capacitor). Note that
series resistance to this pin will drop the supply voltage. The specified sup-
ply voltage range needs to be present on this pin during operation.
Reference oscillator B input. When used with the internal reference oscilla-
tor this pin is connected to an external 26MHz crystal. If an external TCXO
is used, this pin should be floating. This pin possesses a DC voltage and
may require a DC-blocking cap in some applications. DC voltage equal to
VDD when the oscillator is off (OSCM pin low); DC voltage of approximately
1V when used with a crystal; DC voltage of approximately 2.4V when used
with a TCXO. Analog input.
Reference oscillator A input. When used with the internal reference oscilla-
tor this pin is connected to an external 26MHz crystal. If an external TCXO
is used, this pin should be connected to the TCXO output through a decou-
pling capacitor. This pin possesses a DC voltage of approximately 1.25V
and may require a DC-blocking capacitor in some applications. DC voltage
equal to VDD when the oscillator is off (OSCM pin low). Analog input.
No connect.
