GENERAL DESCRIPTION
The EVAL-AD4080-FMCZ is designed to demonstrate the AD4080
performance and provide access to a limited set of AD4080 fea-
tures in the ACE Software environment. The EVAL-AD4080-FMCZ
evaluation kit supports the following AD4080 features:
Low voltage digital signaling (LVDS) data output interface
►
Analog-to-digital converter (ADC) configuration via serial periph-
►
eral interface (SPI)
Internal or external generation of 1.1 V regulated supply rails
►
Sampling rate capability between 1.25 MSPS and 40 MSPS
►
The EVAL-AD4080-FMCZ evaluation board was designed for use
with the Digilent ZedBoard via the field programmable gate array
(FPGA) mezzanine card (FMC) connector. The ZedBoard uses a
Xilinx Zynq7000 system on chip (SoC) that runs Analog Devices,
Inc., Kuiper Linux and LIBIIO included on the SD card supplied in
the evaluation board kit to facilitate communication with the EVAL-
AD4080-FMCZ, enabling ADC configuration and data capture. The
ZedBoard also provides the communication link to the host PC and
the ACE Software plug-in.
