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.
Receive AGC support
Fast detect with low latency for fast AGC control
Signal monitor for slow AGC control
Dedicated AGC support pins
Transmit DPD support
Fine DUC channel gain control and delay adjust
