Analog/Xilinx rapid prototyping kit supports wide band signal processing development

November 13, 2014 // By Graham Prophet
Analog Devices has introduced a rapid prototyping kit today to support design of wide-dynamic-range GSPS data converter-to-FPGA (field-programmable gate arrays) connectivity.

Digital and analogue designers can use the AD-FMCDAQ2-EBZ Rapid Prototyping Kit to quickly prototype the high-speed JEDEC JESD204B SerDes (serialiser/de-serialiser) GSPS data converter-to-FPGA interface on major FPGA platforms, including Xilinx's UltraScale FPGA and Zynq All Programmable SoC devices for radar, instrumentation, wireless radio and other data acquisition applications.

The kit includes an on-board AD9680 dual-channel, 14-bit, 1-Gsample/sec, A/D converter. When converting a 1-GHz input, the A/D converter achieves spurious-free dynamic range (SFDR) performance of 80 dBc and 61.4-dBFS signal-to-noise ratio (SNR) while consuming 1.65 W of total power per channel.

The D/A converter in the kit is the 4-channel, 16-bit, 2.8-Gsample/sec, AD9144, of which two channels are accessed on the board. It features 82-dBc SFDR and a maximum sample rate of 2.8 Gsample/sec, permitting multicarrier generation up to the Nyquist frequency.

The AD9523-1 low-jitter clock generator provides a low-power, multi-output, clock distribution function with low jitter performance, along with an on-chip PLL and VCO with two VCO dividers.

Xilinx notes that the AD-FMCDAQ2-EBZ FMC module offers users of its programmable devices up to 2 GHz of usable analogue bandwidth with a JESD204B interface for rapidly prototyping a variety of wideband RF applications that demand high DSP performance;Xilinx selected this module for its forthcoming Kintex UltraScale DSP kit.

The AD-FMCDAQ2-EBZ is a prototyping system in an FMC form factor for verifying hardware and processing algorithms and rapidly moving from prototype to production in order to reduce the time and risk associated with designing wideband RF signal processing systems. Its performance, bandwidth and integrated functionality allow designers to achieve better signal acquisition in congested RF environments over a wider bandwidth with optimum dynamic range and noise performance.

The AD-FMCDAQ2-EBZ provides tested reference designs including ultra-high-speed data converters, driver amplifiers, clocks and power management ICs. Also included are HDL (hardware description language) code, device drivers, an eye analyser tool and online support at ADI’s EngineerZone online technical support community.
