API Function

Input Parameters

Description

adi_ad9083_rx_

datapath_config_set()

&ad9083_dev: (device structure pointer)

mode: determines datapath flow, refer

to enumeration

adi_ad9083_datapath_mode_e for

exact details

dec: array of decimation value choices

including CIC decimation, J decimation,

G averaging value and H decimation

nco_freq_hz: NCO shift frequency

desired

Configures the digital datapath of the ADC based on the

desired signal path flow (determined by the mode input

parameter), the decimation rates chosen, and the NCO

frequency shift (if used). The valid adi_ad9083_datapath_

mode_e enumeration values are as follows:

AD9083_DATAPATH_ADC_CIC: ADC

→ CIC → JESD204B

Output

AD9083_DATAPATH_ADC_CIC_NCO_J: ADC

→ CIC →

NCO

→ J Decimation → JESD204B Output

AD9083_DATAPATH_ADC_CIC_J: ADC

→ CIC → NCO → J

Decimation

→ JESD204B Output

AD9083_DATAPATH_ADC_J: ADC

→ J Decimation →

JESD204B Output

AD9083_DATAPATH_ADC_CIC_NCO_G: ADC

→ CIC →

NCO

→ G average samples → JESD204B Output

AD9083_DATAPATH_ADC_CIC_NCO_G_H: ADC

→ CIC →

NCO

→ G average samples → H Decimation → JESD204B

Output

adi_ad9083_jtx_startup()

&ad9083_dev: (device structure pointer)

&jtx_param: pointer to array of

JESD204B parameter settings for

desired mode operation

Configures the JESD204B interface with the SERDES

parameters for the desired configuration. Array inputs are:

{L, F, M, S, HD, K, N, NP, CF, CS, DID, BID, LID, SC, SCR},

where SC = subclass

These API function calls are all that are needed to set up the

device. All lower level SPI writes are handled by the API

function calls underneath these high level calls and are

abstracted to make configuration easier for the user. More

detailed information about each of these API function calls and

the lower level SPI configuration included in the source code

can be found in the AD9083 API specification document,

which is provided with the API source code. This source code

package can be requested through the instructions provided at

the AD9083 product page.
