GENERAL DESCRIPTION

The mixed signal front-end (MxFE®) is a highly integrated device

with a 16-bit, 12 GSPS maximum sample rate, RF digital-to-analog

converter (DAC) core, and 12-bit, 6 GSPS rate, RF analog-to-

digital converter (ADC) core. The AD9082 supports four

transmitter channels and two receiver channels. The AD9082

is well suited for applications requiring both wideband ADCs

and DACs to process signal(s) having wide instantaneous

bandwidth. The device features a 16 lane, 16.22 Gbps JESD204C

or 15.5 Gbps JESD204B data transceiver port, an on-chip clock

multiplier, and a digital signal processing (DSP) capability

targeted at either wideband or multiband, direct to RF

applications. The AD9082 also features a bypass mode that

allows the full bandwidth capability of the ADC and/or DAC

cores to bypass the DSP datapaths. The device also features low

latency loopback and frequency hopping modes targeted at

phase array radar system and electronic warfare applications.
