Apollo MxFE Quad, 16-Bit, 28GSPS RF DAC and Quad, 12-Bit, 20 GSPS RF ADC

The mixed signal front-end (Apollo MxFE®) is a highly integrated device with a 16-bit, 28GSPS maximum sample rate, RF digital-to-analog converter (DAC) core, and 12-bit, 20GSPS maximum sample rate, RF analog-to-digital converter (ADC) core. The AD9084 supports four transmitter channels and four receiver channels. The AD9084 is well suited for applications requiring both wideband ADCs and DACs to process signal(s) having wide instantaneous bandwidth. The device features a 48 lane, 28.21Gbps JESD204C or 20Gbps 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 AD9084 also features a bypass mode that allows the full bandwidth capability of the ADC and/or DAC cores to bypass the DSP data-paths. The device also features low latency loopback and frequency hopping modes targeted at phased array radar systems and electronic warefare applications.

The AD9084 is available in a 24mm × 26mm, 899-ball BGAED.
