The mixed signal front end (MxFE®) is a high integration device with a 16-bit, 12 GSPS maximum sample rate radio frequency (RF) digital-to-analog converter (DAC) core and a 12-bit, 4 GSPS rate RF analog-to-digital converter (ADC) core. The AD9081 features a 16-lane, 24.75 Gbps JESD204C or 15.5 Gbps JESD204B data transceiver port, an on-chip clock multiplier, and digital signal processing capability targeted at single- and dual-band direct-to-RF radio applications.

The AD9081 supports four transmitter channels and four receiver channels with a 4D4A configuration. The receiver ADC channels can be shared with observation channels in time division duplex (TDD) operating mode. The AD9081 directly addresses the emerging base station applications with high integration and common platform requirements. The device has flexible inter-polation/decimation configurations that enable direct-to-RF multiband radio applications. AD9081 supports a complex transmi...
