The AD9213 is a single 12-bit， 10.25 GSPS， RF analog-to-digital converter （ADC） with a 6.5 GHz input bandwidth. The AD9213 has been optimized to support high dynamic range frequency and time domain applications requiring wide instantaneous bandwidth and low code error rates （CER）。 The AD9213 features a 16-lane JESD204B interface to support its maximum bandwidth capability.

The AD9213 achieves industry leading dynamic range and linearity performance while consuming only 5 W. Based on an interleaved pipeline architecture， the AD9213 features a proprietary calibration and randomization technique that suppresses interleaving spurious artifacts into its noise floor. The excellent linearity performance of the AD9213 is preserved by a combination of on-chip dithering and calibration resulting in excellent spurious free performance over a wide range of input signal conditions.

Applications requiring less instantaneous bandwidth can benefit from the on-chip digital signal processing （DSP） capability of the AD9213 that reduces the output data rate along with the number of JESD204b lanes required to support it. The DSP path includes a digital downconverter （DDC） with a 48-bit， numerically controlled oscillator （NCO） followed by an I and Q digital decimator stage allowing for selectable decimation rates that are factors of two or three. For fast frequency hopping applications， the AD9213 NCO supports up to 16-profile settings with separate trigger input allowing for wide surveillance frequency coverage but at a reduced JESD204B lane count.

The AD9213 also supports sample accurate multichip synchronization that also includes synchronization of the NCOs. The AD9213 will be offered in a 192 flip-chip ball grid array （FcBGA） package. The AD9213 is specified over a junction temperature range of ?10℃ to +115℃。

The ADS8-V1 Evaluation Board was developed to support the evaluation of Analog Devices High Speed Data Converters with JESD204B bit rates up to 16Gbps. This Wiki site provides a high level overview of the platform. In addition， each use-case of the board has its own section （e.g. Using the ADS8-V1 for High Speed A/D Converter Evaluation）。 The ADS8-V1 is intended to be used only with specified Analog Devices Evaluation Boards. The ADS8-V1 is not intended to be used as a general purpose development platform， and no support is available for standalone operation. The ADS8-V1 may contain hardware features not fully productized or supported by our default customer evaluation configurations. Please refer to Xilinx and its approved distributors for general purpose FPGA Development Kits.

When connected to a specified Analog Devices high speed adc evaluation board， the ADS8-V1 works as a data acquistion board. Designed to support the highest speed JESD204B A/D Converters， the FPGA on the ADS8-V1 acts as the data receiver， while the ADC is the data transmitter. A typical test setup is shown below.
