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.

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.

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.

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.

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.

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
