AD7606X-FMCZ HDL project
|

|
|
===============================================================================
|

|
|
|
||
|
|
Overview
|
||
|
|
-------------------------------------------------------------------------------
|
||
|
|
|
||
|
|
The :adi:`AD7606` is a 8-/6-/4-Channel DAS with 16-Bit, Bipolar Input,
|
||
|
|
Simultaneous Sampling ADC. Each part contains analog input clamp protection, a
|
||
|
|
second-order antialiasing filter, a track-and-hold amplifier, a 16-bit charge
|
||
|
|
redistribution successive approximation analog-to-digital converter (ADC), a
|
||
|
|
flexible digital filter, a 2.5 V reference and reference buffer, and high speed
|
||
|
|
serial and parallel interfaces. The :adi:`AD7606` operate from a single 5 V
|
||
|
|
supply and can accommodate ±10 V and ±5 V true bipolar input signals while
|
||
|
|
sampling at throughput rates up to 200 kSPS for all channels. The input clamp
|
||
|
|
protection circuitry can tolerate voltages up to ±16.5 V. The AD7606 has 1 MΩ
|
||
|
|
analog input impedance regardless of sampling frequency. The single supply
|
||
|
|
operation, on-chip filtering, and high input impedance eliminate the need for
|
||
|
|
driver op amps and external bipolar supplies.
|
||
|
|
|
||
|
|
The :adi:`AD7606C` is a directly pin replacement (software and hardware) for
|
||
|
|
both AD7608 and AD7609, with higher input impedance, throughput rate and
|
||
|
|
extended temperature range with additional features such as 16/18-bit sample
|
||
|
|
size, system gain/offset/phase calibration, sensor disconnect detection,
|
||
|
|
lower Vdrive operation, diagnostics, additional oversampling ratios and per
|
||
|
|
channel analog input range selection with bipolar differential, bipolar
|
||
|
|
single-ended and unipolar single-ended options.
|
||
|
|
|
||
|
|
The :adi:`EVAL-AD7606B-FMCZ <EVAL-AD7606B-FMCZ>` and
|
||
|
|
:adi:`EVAL-AD7606C-18 <EVAL-AD7606C-18>` evaluation boards are designed to
|
||
|
|
help users to easily evaluate the features of :adi:`AD7606B`,
|
||
|
|
:adi:`AD7606C-16` and :adi:`AD7606C-18` analog-to-digital converters (ADCs).

Block design
|
||
|
|
-------------------------------------------------------------------------------
|
||
|
|
|
||
|
|
The data path of the HDL design is simple as follows:
|
||
|
|
|
||
|
|
- the parallel interface is controlled by the
|
||
|
|
:dokuwiki:`axi_ad7606x <resources/fpga/docs/axi_ad7606x>` IP core
|
||
|
|
- the serial interface is controlled by the :ref:`SPI_Engine <spi_engine>`
|
||
|
|
Framework
|
||
|
|
- data is written into memory by a DMA (:ref:`axi_dmac core <axi_dmac>`)
|
||
|
|
- all the control pins of the device are driven by GPIOs
|
||
|

Configuration modes
|
||
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
|
|
||
|
|
The INTF configuration parameter defines the interface type (Serial or Parallel).
|
||
|
|
By default it is set to 0. Depending on the required interface mode, some
|
||
|
|
hardware modifications need to be done on the board and/or ``make`` command:
|
||
|
|
|
||
|
|
In case of the **PARALLEL** interface:
|
||
|
|
|
||
|
|
.. code-block::
|
||
|
|
|
||
|
|
make INTF=0
|
||
|
|
|
||
|
|
In case of the **SERIAL** interface:
|
||
|
|
|
||
|
|
.. code-block::
|
||
|
|
|
||
|
|
make INTF=1
|
||
|
|
|
||
|
|
.. note::
|
||
|
|
|
||
|
|
This switch is a **hardware** switch. Please rebuild the design if the
|
||
|
|
variable has been changed.
|
||
|
|
|
||
|
|
- JP5 - Position A - Serial interface
|
||
|
|
- JP5 - Position B - Parallel interface
|
||
|
|
|
||
|
|
The DEV_CONFIG configuration parameter defines the device which will be used:
|
||
|
|
- Options: 0 - AD7606B, 1 - AD7606C-16, 2 - AD7606C-18.
|
||
|
|
By default it is set to 0.
|
||
|
|
|
||
|
|
The NUM_OF_SDI configuration parameter defines the number of SDI lines used:
|
||
|
|
- Options: 1, 2, 4, 8.
|
||
|
|
By default is set to 8.
|
||
|
|
|
||
|
|
The EXT_CLK configuration parameter defines the external clock option for
|
||
|
|
the ADC clock:
|
||
|
|
- Options: 0 - No, 1 - Yes.
|
||
|
|
By default is set to 0.

Building the HDL project
|
||
|
|
-------------------------------------------------------------------------------
|
||
|
|
|
||
|
|
The design is built upon ADI's generic HDL reference design framework.
|
||
|
|
ADI does not distribute the bit/elf files of these projects so they
|
||
|
|
must be built from the sources available :git-hdl:`here <main:/>`. To get
|
||
|
|
the source you must
|
||
|
|
`clone <https://git-scm.com/book/en/v2/Git-Basics-Getting-a-Git-Repository>`__
|
||
|
|
the HDL repository, and then build the project as follows:.
|
||
|
|
|
||
|
|
**Linux/Cygwin/WSL**
|
||
|
|
|
||
|
|
.. code-block::
|
||
|
|
:linenos:
|
||
|
|
|
||
|
|
user@analog:~$ cd hdl/projects/ad7606x_fmc/zed
|
||
|
|
user@analog:~/hdl/projects/ad7606x_fmc/zed$ make DEV_CONFIG=2 INTF=0
|
||
|
|
|
||
|
|
The result of the build, if parameters were used, will be in a folder named
|
||
|
|
by the configuration used:
|
||
|
|
|
||
|
|
if the following command was run
|
||
|
|
|
||
|
|
``make DEV_CONFIG=2 INTF=0``
|
||
|
|
|
||
|
|
then the folder name will be:
|
||
|
|
|
||
|
|
``DEVCONFIG2_INTF0``
|
||
|
|
|
||
|
|
