## Function Documentation

## 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
