+Supported Evaluation Boards
+---------------------------

+- :adi:`EVAL-AD9083`
+
+Overview
+--------
+
+The AD9083 is a 16-channel, 125 MHz bandwidth, continuous time Σ-Δ
+(CTSD) ADC with an integrated programmable antialiasing filter and
+termination resistor, making it suitable for low power applications in a
+compact form. Each ADC core features a CTSD modulator with background
+nonlinearity correction and dither for noise reduction. It supports
+differential signals for analog and clock inputs. Signal processing
+includes cascaded integrator comb (CIC) filters and quadrature digital
+downconverters (DDCs) for effective band-shaped noise suppression. The
+ADC boasts high-speed serialized outputs via a Subclass 1 JESD204B
+interface, supporting various lane configurations. Synchronization
+across multiple units is possible using SYSREF, TRIG, and SYNCINB pins.
+The AD9083 allows power savings through flexible power-down modes and is
+configurable via a 1.8V-capable 3-wire SPI interface. It is housed in a
+100-ball CSP_BGA package, designed to operate in temperatures from -40°C
+to +85°C.

+Hardware Specifications
+-----------------------
+
+Power Supply Requirements
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The AD9083 evaluation board requires external power sources, as it lacks
+internal power management for autonomous operation. It relies on
+external supplies for power domains such as AVDD, AVDD1P8, DVDD, and
+DVDD1P8, which have specific voltage and tolerance requirements. No
+provisions are integrated into the board for powering it internally
+without these external inputs.
+
++-----------------+-----------------+----------------+
+| Domain          | Voltage (V)     | Tolerance (%)  |
++-----------------+-----------------+----------------+
+| AVDD            | 1.0             | ±5             |
++-----------------+-----------------+----------------+
+| AVDD1P8         | 1.8             | ±5             |

+No-OS Build Setup
+-----------------
+
+Please see: `https://wiki.analog.com/resources/no-os/build`
+
+No-OS Supported Examples
+------------------------
+
+The initialization data used in the examples is taken out from the 
+`Project SRC Path <https://github.com/analogdevicesinc/no-OS/tree/main/projects/ad9083/src>`__ .
+
+IIO example
+~~~~~~~~~~~
+
+This project is actually an IIOD demo for the EVAL-AD9083 evaluation
+board. The project launches the IIOD server on the board, so that the
+user may connect to it via an IIO-Oscilloscope Client app. Using the
+IIO-Oscilloscope, the user can read samples from the device.
+
+If you are not familiar with ADI IIO Application, please take a look at:
+:dokuwiki:`IIO No-OS </resources/tools-software/no-os-software/iio>`
+
+If you are not familiar with ADI IIO-Oscilloscope Client, please take a
+look at: :dokuwiki:`IIO Oscilloscope </resources/tools-software/linux-software/iio_oscilloscope>`.
+
+The No-OS IIO Application together with the No-OS IIO AD9083 driver take
+care of all the back-end logic needed to setup the IIO server.
+
+This example initializes the IIO device and calls the IIO app as shown
+in the `IIO Example <https://github.com/analogdevicesinc/no-OS/blob/main/drivers/adc/ad9083/iio_ad9083.c>`__ .
+
+In order to build the IIO project make sure you have the following
+configuration in the 
+`Makefile <https://github.com/analogdevicesinc/no-OS/blob/main/projects/ad9083/Makefile>`__ .
+
+.. code-block:: bash
+
+   # Select the example you want to enable by choosing y for enabling and n for disabling

+
+Used Hardware
+^^^^^^^^^^^^^
+
+- AD9083 Evaluation Board
+- Zynq ZCU102 (Xilinx)
+
+Connections
+^^^^^^^^^^^
+
+Use the HPC FMC connectors to establish a connection between the
+EVAL-AD9083 and ZCU102 boards. Make sure to correctly interface the
+ZCU102 HPC connectors (J4, J5) with EVAL-AD9083. Configure the I/O
+standards and voltage levels, typically setting FMC connections to 1.8V.
+To power up the Zynq ZCU102 board, ensure the main power switch (SW1) is
+initially in the “OFF” position. Connect the power supply to the power
+connector J52 on the board. Turn switch SW1 to the “ON” position to
+power the board, at which point LED DS2 will illuminate, indicating
+successful power supply. Verify correct polarity and voltage levels to
+prevent damage. For further configuration, including switch settings and
+connector interfaces, refer to the ZCU102 Evaluation Board User Guide.
