◆ 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: 0 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:

◆ ad9739a_setup()

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,
		uint8_t	register_value
	)

Writes a value to the selected register.

Parameters

dev	- The device structure.
register_address	- The address of the register to write to.
register_value	- The value to write to the register.

Returns: Returns 0 in case of success or negative error code.

Here is the caller graph for this function:

◆ 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 )

Delay for a number of fdata clock cycles.

Parameters

cycles - Number of cycles to wait for.

Returns: Returns negative error code or 0 in case of success.
