AFE7222IRGCR

The AFE7222IRGCR from Texas Instruments is a wideband mixed-signal transceiver designed for radio applications. This Analog Front End (AFE) integrates dual 12-bit DACs operating up to 130 MSPS and dual 12-bit ADCs operating up to 65 MSPS. It supports both full- and half-duplex operation, offering flexibility for various radio designs.

The device features a 12-bit resolution across its DAC and ADC channels, providing precise signal conversion. It offers multiple interface options, including Serial LVDS and Interleaved Parallel CMOS, facilitating integration into different system architectures. The AFE7222IRGCR operates over a wide temperature range from -40°C to 85°C and is built on a low-power analog CMOS process.

Key digital features include interpolation for the TX path and decimation for the RX path, quadrature modulation correction (QMC), and independent NCOs for RX and TX paths. Auxiliary 12-bit DACs and a dual-input auxiliary ADC are also available for control and monitoring functions. The device is housed in a compact 64-pin VQFN package measuring 9mm x 9mm, suitable for space-constrained applications.

Applications for the AFE7222IRGCR include portable, low-power radios, wireless infrastructure, point-to-point radio systems, and pico-cell base stations. Its combination of performance, low power consumption, and integrated features makes it a versatile solution for modern radio communication systems.
