DESCRIPTION
The AFE7225/7222 is an analog front end designed for full- or half-duplex radios. Over-sampling transmit
12-bit DACs provide output frequencies from baseband to Nyquist. Under-sampling receive 12-bit ADCs
allow analog inputs from baseband to ~230MHz. Most blocks within the AFE7225/7222 are independently
controlled for optimization of power consumption versus utilization. Two auxiliary control 12-bit DACs and
a dual input auxiliary monitoring 12-bit ADC are available via serial interface. Digital features include QMC
(quadrature modulation correction), interpolation, decimation, RMS/peak power meter and mixers with
independent NCOs for RX and TX path.
The AFE7225/7222 is available in a 64-pin 9x9mm QFN package (RGC). The AFE7225/7222 is built on
Texas Instrument’s low power analog CMOS process and is specified over the full industrial temperature
range (–40°C to 85°C).
