Analog – Data converter FMC boards connect to new series FPGA evaluation kits (Data Converter FMC boards)Jan 31 2012 - Design & Manufacture [More Design & Manufacture Articles]
Analog Devices (ADI) has introduced two data converter FMC boards (FPGA mezzanine cards) that connect to Xilinx Inc.’s new 28nm 7 series FPGA (field programmable gate array) evaluation kits.
ADI’s high-speed AD9739A D/A converter and AD9467 A/D converter FMC boards support multiple generations of Xilinx kits – including the company’s new Kintex-7 FPGA evaluation kits. The new Analog Devices FMC boards include all of the HDL (hardware description language) code and device drivers needed for designers to engage in rapid prototyping and reduce development time and risk, says the company.
“ADI’s new FMC boards, integration software and industry-leading data conversion expertise help engineers designing with Xilinx’s Kintex-7 series FPGAs to move more quickly through system prototyping and get their products to market faster,” said Dave Babicz, director of Global Alliances, Analog Devices. “At the same time, our new boards are backward compatible with other Xilinx FPGAs, which means that engineers will be able to design products that meet a range of performance criteria using a simplified design environment.”
Raj Seelam, senior marketing manager, targeted design platforms, Xilinx, said: “Xilinx’s Targeted Design Platforms accelerate system development and integration by providing the industry’s most comprehensive development kits, which include boards, tools, IP cores, reference designs and FMC support. Our adoption and support for open standards such as FMC and the AMBAR4 AXI IP core interface strengthens the ability of Xilinx Alliance Program members like Analog Devices to deliver key technologies that make it easier for FPGA users to complete their projects.”
ADI’s AD9739A FMC board is based on the AD9739A, a 14-bit D/A converter that enables cable television and broadband operators to synthesise the entire cable spectrum up to 1GHz into a single RF (radio frequency) port, while consuming a maximum of 1.1W of power. The AD9739A 14-bit, 2.5-GSPS D/A converter’s wide bandwidth and dynamic range enable cable operators to increase the QAM (quadrature amplitude modulation) channel densities by 20 times over the densities found in today’s cable modems. Competing D/A converter solutions require an additional 28 LVDS (low-voltage differential signaling) pairs for the data interface.
ADI’s AD9467 FMC board is based on the AD9467, which is a 16-bit, 250-MSPS A/D converter that operates on 35 percent less power at a 25 percent higher sampling rate than any other 16-bit data converter. The AD9467 provides a new level of signal processing performance for test and measurement instrumentation, defence electronics and communications applications where high resolution over a wide bandwidth is needed.
The AD9467 delivers resolution and a fast sample rate while simultaneously achieving a high SFDR (spurious-free dynamic range) of up to 100dBFS and SNR (signal-to-noise ratio) performance of 76.4dBFS. The device’s SFDR of 90dBFS up to 300MHz analog input and 60-femtosecond rms (root mean square) jitter help lower the signal chain bill of materials component count by allowing engineers to increase system performance at higher intermediate frequencies, thereby reducing the number of signal down-conversion stages, says the company.
