The AFE7950 is a high-performance, quad-channel RF sampling transceiver based on 14 and 16-bit, 12-GSPS DACs and 14 and 16-bit, 3-GSPS ADCs. The AFE7950 operates up to X-band RF frequencies. The AFE7950 has 8 of JESD204B compatible SerDes transceivers running up to 15Gbps. The devices have up to two DUCs per TX channel and two DDCs per RX channel, with multiple interpolation and decimation rates and digital quadrature modulators and demodulators with independent, frequency flexible NCOs. Each ADC input path includes a DSA and RF and digital power detectors. Flexible decimation options provide optimization of data bandwidth and can support ADC BW up to 1200 MHz. The DAC signal paths support interpolation and digital up conversion options that deliver up to 2400 MHz of signal bandwidth. The differential output path includes a digital step attenuator (DSA), which provides tuning of output power.
