bladerf_get_pll_enable()

API_EXPORT int CALL_CONV bladerf_get_pll_enable	(	struct bladerf *	dev,
		bool *	enabled )

Fetch the state of the Phase Detector/Frequency Synthesizer

Parameters

	dev	Device handle
[out]	enabled	True if enabled, False otherwise

Returns

0 on success, value from Error codes list on failure

bladerf_get_pll_lock_state()

API_EXPORT int CALL_CONV bladerf_get_pll_lock_state	(	struct bladerf *	dev,
		bool *	locked )

Fetch the lock state of the Phase Detector/Frequency Synthesizer

Parameters

	dev	Device handle
[out]	locked	True if locked, False otherwise

Returns

0 on success, value from Error codes list on failure

bladerf_get_pll_refclk()

API_EXPORT int CALL_CONV bladerf_get_pll_refclk	(	struct bladerf *	dev,
		uint64_t *	frequency )

Get the currently-configured frequency for the reference clock input.

Parameters

	dev	Device handle
[out]	frequency	Reference clock frequency

Returns

0 on success, value from Error codes list on failure

bladerf_get_pll_refclk_range()

API_EXPORT int CALL_CONV bladerf_get_pll_refclk_range	(	struct bladerf *	dev,
		const struct bladerf_range **	range )

Get the valid range of frequencies for the reference clock input

Parameters

	dev	Device handle
[out]	range	Reference clock frequency range

Returns

0 on success, value from Error codes list on failure

bladerf_get_pll_register()

API_EXPORT int CALL_CONV bladerf_get_pll_register	(	struct bladerf *	dev,
		uint8_t	address,
		uint32_t *	val )

Read value from Phase Detector/Frequency Synthesizer

The address is interpreted as the control bits (DB1 and DB0) used to write to a specific latch.

Parameters

	dev	Device handle
[in]	address	Latch address
[out]	val	Value to read from

Returns

0 on success, value from Error codes list on failure

bladerf_set_pll_enable()

API_EXPORT int CALL_CONV bladerf_set_pll_enable	(	struct bladerf *	dev,
		bool	enable )

Enable the Phase Detector/Frequency Synthesizer

Enabling this disables the VCTCXO trimmer DAC, and vice versa.

Parameters

	dev	Device handle
[in]	enable	True to enable, False otherwise

Returns

0 on success, value from Error codes list on failure

bladerf_set_pll_refclk()

API_EXPORT int CALL_CONV bladerf_set_pll_refclk	(	struct bladerf *	dev,
		uint64_t	frequency )

Set the expected frequency for the reference clock input.

Parameters

	dev	Device handle
[in]	frequency	Reference clock frequency

Returns

0 on success, value from Error codes list on failure

bladerf_set_pll_register()

API_EXPORT int CALL_CONV bladerf_set_pll_register	(	struct bladerf *	dev,
		uint8_t	address,
		uint32_t	val )

Write value to Phase Detector/Frequency Synthesizer

The address is interpreted as the control bits (DB1 and DB0) used to write to a specific latch. These bits are masked out in val

Parameters

	dev	Device handle
[in]	address	Latch address
[in]	val	Value to write to

Returns

0 on success, value from Error codes list on failure
