AXI AD9371 (OBSOLETE)#
Warning
This IP is was discontinued, limited support available. Last release for this
IP is hdl_2019_r2
and can be found on our HDL repository, on the branch
with the same name.
Note
This page has a great historical background. The same functionalities are implemented using the generic JESD204 TPL IPs.
The AXI AD9371 IP core can be used
to interface the AD9371 device. An AXI Memory Map interface is used for
configuration. Data is sent in a format that can be transmitted by Xilinx’s
JESD IP. More about the generic framework interfacing ADCs, that contains the
up_dac_channel
, up_adc_channel
and up_dac_common modules
,
up_adc_common modules
can be read in Generic AXI DAC and Generic AXI ADC.
Features#
AXI Lite control/status interface
Hardware and software DC filtering
IQ correction
Internal DDS
Receive and transmit loopback
Supports both Altera and Xilinx devices

DDS_INIT_1_EXTENDED |
RW |
0x0000 |
The extended DDS phase initialization for tone 1. Sets the initial phase offset of the tone. The extended init(phase) value should be calculated according to DDS_PHASE_DW value from CHAN_CNTRL_1 NOT-APPLICABLE if DDS_DISABLE is set (0x1). |

DDS_INCR_1_EXTENDED |
RW |
0x0000 |
Sets the frequency of tone 1’s phase accumulator. Its value can be calculated by \(INCR = (f_{out} * 2^{phaseDW}) * clkratio / f_{if}\); Where f_out is the generated output frequency, DDS_PHASE_DW value can be found in CHAN_CNTRL_1 in case DDS_PHASE_DW is not 16, f_if is the frequency of the digital interface, and clock_ratio is the ratio between the sampling clock and the interface clock. NOT-APPLICABLE if DDS_DISABLE is set (0x1). |

Design Guidelines#
The IP was developed part of the AD9371 chip, that can be found on EVAL-ADRV9371.
The control of the AXI AD9371 chip is done through a SPI interface, using ACE software. The ACE (Analysis - Control- Evaluate) software provides a graphical user interface for configuring and controlling the AD9371, allowing for easy setup and evaluation of the DAC’s performance.
Warning
We do not offer support for ACE anymore. Limited support is available.
