Texas Instruments AFE722x Analog Front End Wideband Transceiver
Texas Instruments AFE722x Analog Front End Wideband Mixed-Signal Transceiver designed for full- or half-duplex radios. AFE722x 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 Texas Instruments AFE722x 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 a serial interface. Digital features include QMC (quadrature modulation correction), interpolation, decimation, RMS/peak power meter, and mixers with independent NCOs for RX and TX paths.Features
