Detailed Description

store the value of all the latch and the input reference frequency

Member Data Documentation

a_n_counter

uint8_t adf4106_settings_t::a_n_counter

a 6 bits counter is supported at ADF4106

anti_backlash_width

uint8_t adf4106_settings_t::anti_backlash_width

The width of the anti-backlash pulse, this pulse ensures that no dead zone is in the PFD transfer function and minimizes phase noise and reference spurs.

b_n_counter

uint16_t adf4106_settings_t::b_n_counter

a 13 bits counter

counter_reset

uint8_t adf4106_settings_t::counter_reset

resets the R and N counters

cp_gain

uint8_t adf4106_settings_t::cp_gain

determines which charge pump current settings is used

cp_type

uint8_t adf4106_settings_t::cp_type

the type of the Charge Pump output

current_setting1

uint8_t adf4106_settings_t::current_setting1

is used when the RF output is stable and the system is in static state

current_setting2

uint8_t adf4106_settings_t::current_setting2

is meant to be used when the system is dynamic and in a state of change (i.e., when a new output frequency is programmed)

fast_lock_mode

uint8_t adf4106_settings_t::fast_lock_mode

set the desired Fast Lock Mode

lock_detect_precision

uint8_t adf4106_settings_t::lock_detect_precision

determines the number of consecutive cycles of phase delay, that must occur before lock detect is set

muxout_control

uint8_t adf4106_settings_t::muxout_control

the type of the MUXOUT output

pfd_max

uint32_t adf4106_settings_t::pfd_max

PFD max frequency

phase_detector_pol

uint8_t adf4106_settings_t::phase_detector_pol

the polarity of the Phase Detector

power_down1

uint8_t adf4106_settings_t::power_down1

activate power down mode

power_down2

uint8_t adf4106_settings_t::power_down2

define the type of the power down

prescaler_value

uint8_t adf4106_settings_t::prescaler_value

the value of the prescaler

ref_counter

uint16_t adf4106_settings_t::ref_counter

The initial value of the 14 bit Reference Counter register

ref_in

uint32_t adf4106_settings_t::ref_in

Reference Input Frequency

test_mode_bits

uint8_t adf4106_settings_t::test_mode_bits

Should be set to zero for Normal operation

timer_counter_control

uint8_t adf4106_settings_t::timer_counter_control

how long will be the secondary charge pump current active, before reverting to the primary current
