Function Documentation

◆ ad9739a_dac_fs_current()

float ad9739a_dac_fs_current ( struct ad9739a_dev dev,
float  fs_val 
)

Sets the full-scale output current for the DAC.

Parameters
dev- The device structure.
fs_val- The desired full-scale output current. Accepted values: 8.7 to 32.7 (mA) and 0. When fs_val is set to 0 the DAC output is disabled(sleep).
Returns
Returns the actual set full-scale current or negative error code.
Here is the caller graph for this function:

◆ ad9739a_power_down()

int32_t ad9739a_power_down ( struct ad9739a_dev dev,
uint8_t  pwr_config 
)

Powers down LVDS interface and TxDAC.

Parameters
dev- The device structure.
pwr_config- Selects the modules to be powered-down. Example: AD9739A_POWER_DOWN_LVDS_DRVR_PD | AD9739A_POWER_DOWN_LVDS_RCVR_PD
Returns
Returns negative error code or 0 in case of success.

◆ ad9739a_read()

int32_t ad9739a_read ( struct ad9739a_dev dev,
uint8_t  register_address,
uint8_t *  register_value 
)

Reads the value of the selected register.

Parameters
dev- The device structure.
register_address- The address of the register to read.
register_value- The value read from the register.
Returns
registerValue - The register's value or negative error code.
Here is the caller graph for this function:

◆ ad9739a_remove()

int32_t ad9739a_remove ( struct ad9739a_dev dev)

Free the resources allocated by ad9739a_setup().

Parameters
dev- The device structure.
Returns
SUCCESS in case of success, negative error code otherwise.

◆ ad9739a_reset()

int32_t ad9739a_reset ( struct ad9739a_dev dev)

Resets the device.

Parameters
dev- The device structure.
Returns
Returns negative error code or 0 in case of success.
Here is the caller graph for this function:

int32_t ad9739a_setup ( struct ad9739a_dev **  device,
struct ad9739a_init_param  init_param 
)

Initializes the AD9739A.

Parameters
device- The device structure.
init_param- The structure that contains the device initial parameters.
Returns
Returns negative error code or 0 in case of success.
Here is the caller graph for this function:

◆ ad9739a_write()

int32_t ad9739a_write ( struct ad9739a_dev dev,
uint8_t  register_address,

◆ ad_serdes_clk()

int32_t ad_serdes_clk ( struct ad9739a_dev dev,
uint8_t  mode 
)

Sets the normal baseband mode or mix-mode.

Parameters
dev- The device structure.
mode- mode of operation. Example: AD9739A_DAC_DEC_NORMAL_BASEBAND - normal baseband mode; AD9739A_DAC_DEC_MIX_MODE - mix-mode.
Returns
Returns negative error code or 0 in case of success.

◆ delay_fdata_cycles()

int32_t delay_fdata_cycles ( uint32_t  cycles)
