Analog Devices has introduced two data converter FMC boards (FPGA mezzanine cards) that connect to Xilinx’s new 28 nm 7 series FPGA (field programmable gate array) evaluation kits.
AD’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 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.
The 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 1 GHz into a single RF (radio frequency) port, while consuming a maximum of 1,1 W. According to AD, the 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, while competing D/A converter solutions require an additional 28 LVDS (low-voltage differential signalling) pairs for the data interface.
The AD9467 FMC board is based on the AD9467, which is a 16-bit, 250 MSps A/D converter. The AD9467 provides a high 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 100 dBFS and SNR (signal-to-noise ratio) performance of 76,4 dBFS. The device’s SFDR of 90 dBFS up to 300 MHz analog input and 60 femtosecond rms 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.
