ADC targets GHz bandwidth applications
This product is featured in EDN's Hot 100 products of 2017. See all 100 here.
With sampling speeds of up to 3 Gsamples/s, the converter facilitates direct RF signal-processing architectures and delivers high oversampling. This simplifies front-end filtering, reducing receiver design complexity and overall system cost. The converter furnishes Subclass 1 JESD204B-coded serial digital output that is user-configurable for one-lane, two-lane, four-lane, or eight-lane operation, with lane rates of up to 16 Gbps/lane. Using default settings, total power per channel at 3 Gbps is 1.65 W.
The AD9208 ADC integrates four wideband decimation filter and NCO blocks supporting multiband receivers, a temperature diode for system thermal management, and a three-wire serial port interface. Housed in a 12×12 mm, 196 lead BGA package and specified over an ambient temperature range of -40°C to +85°C, the AD9208 costs $1326.
