AFE7222IRGCT

Analog Front End (AFE) Overview

The AFE7222IRGCT is a wideband mixed-signal transceiver from 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 handling 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) Procurement Notes

Verify the specific suffix IRGCT against official Texas Instruments documentation to confirm package type, temperature range, and tape-and-reel specifications. Ensure compatibility with system requirements for serial interface control and power management optimization.

Analog Front End (AFE) Selection Notes

Select this component when designing wideband transceivers requiring integrated high-speed data conversion and digital correction features. Consider the independent block control for power consumption optimization versus utilization needs. Verify that the baseband to ~230MHz input/output frequency ranges meet system bandwidth requirements.
