Texas Instruments AFE7222 Analog Front End Wideband Mixed-Signal Transceiver
Texas Instruments AFE7222 Analog Front End Wideband Mixed-Signal Transceiver designed for full- or half-duplex radios. TI AFE7222 includes over-sampling transmit 12-bit DACs that provide output frequencies from baseband to Nyquist. This AFE transceiver also features under-sampling receive 12-bit ADCs that allow analog inputs from baseband to ~230MHz. Most blocks within the AFE7222 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.
