Example frequency formats:\n\n1\n25e6\n100e6 / 3\n\n3. Select interface type. AC or DC buffer is auto-seletected based on reference frequency. If reference frequency is below 5 MHz, then use DC buffer. Otherwise, use AC buffer. To select interface types for AC buffer, refer to the 'Interface Type Selection Tips' in the XO wizard page. The same can be applied to PRIREF and SECREF.\n\n4. Select the input switching mode. The input switching mode is auto-seletected based on the states of PRIREF and SECREF enable. When both references are enabled, then Auto non-revertive is selected. If only one reference is enabled, then manual holdover is selected. However, it is highly recommended to read through the 'Input Switching Mode Selection Guide' in this wizard page and make the decision.\n\n5. If manual fallback or manual holdover is selected, then choose between manually select by register and manually select by REFSEL pin. btn_page4_back= btn_ref_validation_show_instructions=Show Instructions sPRIREF_ACCURACY_PPM=15 sPRIREF_AVG_COUNT=2 sPRIREF_EARLY_MARGIN=0 sPRIREF_EARLY_calc=4.80 ns sPRIREF_LATE=32262 sPRIREF_LATE_MARGIN=54 sPRIREF_LATE_calc=1.29 ms sPRIREF_PH_VALID_calc=n/a sPRIREF_PPM_INVALID=26 sPRIREF_PPM_TIMER=n/a sPRIREF_PPM_VALID=20 sSECREF_ACCURACY_PPM=15 sSECREF_AVG_COUNT=2 sSECREF_EARLY_MARGIN=0 sSECREF_EARLY_calc=n/a sSECREF_LATE=32262 sSECREF_LATE_MARGIN=54 sSECREF_LATE_calc=n/a sSECREF_PH_VALID_calc=n/a sSECREF_PPM_INVALID=26 sSECREF_PPM_TIMER=n/a sSECREF_PPM_VALID=20 s_wizard_reference_validation_message_box=INSTRUCTIONS:\n\nIf DPLL is disabled, then skip this page.

For 1-pps input, only enable the 1-pps phase detector and disable all other detectors.\n\n1. Validation timer. The reference must stay valid for 'validation timer' amount of time before it's considered valid. It is recommended to set the validation timer to more than twice of the total reference validation measurement time. The frequency detection measurement time is displayed on the wizard. Measurement time of amplitude detection, early / late clock detection as well as 1-pps phase detection is roughly one cycle of reference clock. Therefore, if the reference frequency is >= 2 kHz, total measurement time is approximately the frequency detection measurement time. If the reference frequency is < 2 kHz, total measuremnet time is approximately 1 cycle of reference clock.\n\n2. Amplitude detector. There are two modes: amplitude detector mode and CMOS slew rate detector mode. In amplitude detector mode, the reference is considered valid if the signal swing is higher than the selected threshold. In CMOS slew rate detector mode, the detection method can be either slew rate detection or VIH / VIL detection. For slew rate detection, the input slew rate must be faster than 0.2 V/ns. For VIH / VIL detection, the input high level must be above 1.8 V and the low level must be below 0.6 V. The amplitude detection mode cannot be used for reference frequencies less than 5 MHz. If the reference frequency is above 5 MHz, then amplitude detection mode is recommended for differential input and the CMOS slew rate detection mode is recommended for single-ended input. If the input swing is too low (for example, the LVDS voltage swing is 400 mV, very marginal compared to the mininum threshold of amplitude detection mode), then amplitude detector can be disabled.\n\n3. Frequency detector. This detector is only valid for PRIREF / SECREF frequencies >= 2 kHz. Frequency detection needs 4 parameters: valid threshold in ppm, invalid threshold in ppm, accuracy in ppm and average count. The PRIREF or SECREF is considered valid if the frequency error between PRIREF / SECREF and XO is within the valid threshold. While it's frequency valid, it's considered as frequency invalid if the frequency error exceeds the invalid threshold. The accuracy in ppm indicates how accurate the valid and invalid threshold can be. In other words, this is the resolution of valid and invalid threshold counters. The minimum average count is 2. Keep it as 2 unless the reference clock has too much wander and the DPLL loop bandwidth is too narrow. In that case, raise the average count to no more than 10. As mentioned, the '0-error' reference for frequency detection is the XO. In reality, of course, the XO frequency is not '0-error'. Therefore, the valid and invalid thresholds must take the XO ppm error into account. The minimum valid threshold should be max XO frequency error + max PRIREF / SECREF frequency error + accuracy in ppm. The minimum invalid threshold should be valid threshold + accuracy in ppm.\n\n4. Early and late clock window detector. This detector is only valid for PRIREF / SECREF frequencies >= 2 kHz. 3 parameters are needed: early counter, late counter and number of missing clocks. After setting early and late counters, the T_early and T_late are calculated accordingly. As shown in the timing diagram, the PRIREF / SECREF is considered valid if its next clock edge falls within ideal next edge - T_early and ideal next edge + T_late. Setting the number of missing clocks to x is equivalent to adding x * reference_clock_period to T_late. So the number of missing clocks is typically set to 0 unless gapped clock needs to be supported. The early and late clock detector uses divided down BAW VCO frequency as its '0-error' reference. However, since this is a very coarse detection method (resolution of T_early and T_late counter is roughly 1.6 ns), the ppm error of the BAW VCO itself is not of concern.\n\n5. 1-pps phase detector. This detector is only valid for PRIREF / SECREF frequencies < 2 kHz. T_jitter is auto-calculated according to the phase detector counter. As shown in the timing diagram, the PRIREF / SECREF is considered valid if the next clock edge falls within ideal next edge - T_jitter and ideal next edge + T_jitter. Note that the '0-error' clock reference for 1-pps phase detector is the XO, so T_jitter must be greater than the sum of: (1) XO phase error accumulated through one PRIREF / SECREF clock period (for example, 1 second for 1-pps input). This includes the phase error caused by frequency inaccuracy, accumulated jitter as well as wander. (2) The max period jitter of PRIREF / SECREF. Therefore, low frequency and high stability XO is recommended for 1-pps input. This is because for XOs with the same frequency stability, the one with the lower frequency accumulates less phase error over fixed period of time. 12.8 MHz TCXO / OCXO is recommended for 1-pps input.\n\n DPLL_VCO_freq=2500 bRUN_SCRIPT=Run Script btn_dpll_show_instructions=Show Instructions btn_page5_back= btn_restore_dpll_reg=Restore Calculated DPLL Settings cb_show_dpll_registers=0 combo_disable_fastlock=0 combo_set_max_tdc_freq=0 combo_switching_method=0 sDPLL_LBW=100 sDPLL_LBW_ACT=101.4 sDPLL_PEAK=0.1 sDPLL_PEAK_ERROR=1 sMAX_TDC_freq=26000000 sPRIREF_freq_display=19.2 MHz sSECREF_freq_display=Disabled sTDC_freq=19.2 MHz s_wizard_dpll_message_box=DPLL calculation completed!\n\nTDC frequency = 19200000\n\nPlanned VCO1 frequency = 2500000000\nActual VCO1 frequency = 2500000000\nPLL1 frequency error = 0 ppb\n\nPlanned VCO2 frequency = 5898240000\nActual VCO2 frequency = 5898240000\nPLL2 frequency error = 0 ppb\n\nDPLL fastlock time = 61.44 ms + 6.19 ms = 67.63 ms\n\nTotal DPLL frequency lock time ~= DPLL fastlock time + 2 * DPLL frequency lock measurement time\n\nTotal DPLL phase lock time ~= DPLL fastlock time + 2 * DPLL phase lock measurement time BAW_LOCK_PPM_THRESH=5 BAW_UNLK_PPM_THRESH=10 DPLL_PL_LOCK_calc=278.26 ps DPLL_PL_UNLK_calc=4.45 ns btn_baw_lock_detect_default=Set Default btn_dpll2_show_instructions=Show Instructions btn_dpll_freq_lock_detect_default=Set Default btn_history_recommend=Min Values Required btn_page6_back= btn_ph_threshold_recommend=Recommended sBAW_LOCK_ACCURACY_PPM=1 sBAW_LOCK_AVG=2 sBAW_TMEAS_LOCK_calc=19.2000 ms sDPLL_HISTCNT_calc=109.23 ms sDPLL_HISTDLY_calc=19.20 ms sDPLL_LOCK_ACCURACY_PPM=1 sDPLL_LOCK_AVG=10 sDPLL_LOCK_PPM=1 sDPLL_PL_MEAS_TIME=9.86 ms sDPLL_TMEAS_LOCK_calc=96.0000 ms sDPLL_UNLK_PPM=10 s_wizard_dpll2_message_box=INSTRUCTIONS:\n\nAll lock detect settings are set to either default or recommended values after the DPLL script is run. Still, it is highly recommended to go through the instructions and make the adjustments.\n\n1. BAW frequency lock detect. Disable this if DPLL is enabled. This detector is only useful if the DPLL is disabled and the device works in free-running mode. Enter lock threshold in ppm, unlock threshold in ppm, average count (min value = 2) and accuracy in ppm. The BAW (VCO1) is considered to be locked if the frequency error between the BAW and the XO is within lock threshold. Once the BAW is locked, it's considered to be unlocked if the frequency error exceeds the unlock threshold. The step size of lock and unlock threshold in ppm = accuracy / average. If there's no specific requirement for BAW lock detect, click 'Set Default'.\n\n2. DPLL frequency lock detect. Enter lock and unlock thresholds in ppm, average count (min value = 2) as well as accuracy in ppm. The DPLL is considered to be frequency locked if the frequency error between the VCO1 and the references is within the lock threshold. While the DPLL is frequency locked, it's considered to be frequency unlocked if the frequency error exceeds the unlock threshold. The step size of lock and unlock threshold = accuracy / average. If there's no specific requirement for DPLL frequency lock detect, click 'Set Default'.\n\n3. DPLL phase lock detect. Set lock and unlock threshold counters. The actual lock and unlock thresholds in second are then calculated accordingly. The DPLL is considered as phase locked if the phase difference between the two inputs of TDC (divided reference and divided VCO1) is within the lock threshold. While the DPLL is phase locked, it's considered as phase unlocked if the phase difference exceeds the unlock threshold. Use recommended values for this. The lock and unlock counters should not be manually set, and they are only used for engineering debugging purposes.\n\n4. Tuning word history. This block sets the tuning word history for holdover. Set history counter and delay counter. The averaging time and delay time are then auto-calculated. Refer to datasheet section '9.3.7.4 Tuning Word History' for details. If there's no specific requirement for holdover tuning word, click 'Min Values Required'. This makes sure that the delay time is more than 8 times of the reference frequency validation measurement time, and that the averaging time is longer than the delay time.\n\n btn_page7_back=
