AFE7222IRGCR

Analog Front End (AFE) Overview

The AFE7222IRGCR is a wideband mixed-signal transceiver within the Texas Instruments AFE722x family, designed for full- or half-duplex radio systems. It integrates over-sampling transmit 12-bit DACs supporting output frequencies from baseband to Nyquist and under-sampling receive 12-bit ADCs accommodating analog inputs from baseband to approximately 230MHz. Key digital features include quadrature modulation correction (QMC), interpolation, decimation, RMS/peak power metering, and mixers with independent numerically controlled oscillators (NCOs) for RX and TX paths. The device also provides two auxiliary control 12-bit DACs and a dual-input auxiliary monitoring 12-bit ADC via a serial interface.

Analog Front End (AFE) Feature Summary

• Integrated wideband transceiver with 12-bit oversampling TX DACs and undersampling RX ADCs
• Digital signal processing including QMC, interpolation, decimation, and power metering
• Independent NCOs for RX and TX mixer paths
• Auxiliary I/O with dual 12-bit DACs and 12-bit ADC

Analog Front End (AFE) Applications

• Full-duplex radio systems
• Half-duplex radio systems
• Wideband communication transceivers

Analog Front End (AFE) Part Context

The AFE7222IRGCR belongs to the AFE722x series of analog front ends. This family is characterized by independently controllable blocks to optimize power consumption relative to utilization. The specific part number denotes the industrial temperature range variant in a VQFN package, distinct from evaluation modules like the AFE7222EVM which are used for development purposes.
