2024年3月13日 · VCO_SEL=2 and VCO_CAPCTRL=0 represents the lowest frequency on VCO2. VCO_SEL=2 and VCO_CAPCTRL=191 represents the highest frequency on VCO2. etc; The …

I can't find any estimation formula of VCO_CAPCTRL & VCO_DACISET of LMX2820. Without this, i don't know how to do VCO calibration through partial assist method. Could you please …

The LMX2592 does not have the same function of readback for the CAPCTRL so cannot do the method of auto-calibration and just readback what the CAPCTRL value found is. To find the …

It would appear that registers R68[7:5] is the selected VCO_SEL, R69[7:0] is the selected VCO_CAPCTRL, and R70[8:0] the selected VCO_IDAC after internal calibration. Can TI …

12 - set VCO_CAPCTRL_FORCE = 1 and VCO_DACISET_FORCE = 1 (write reg 8 with 0x6800) 13 - set VCO_SEL_FORCE = 1 and VCO_SEL = binary 011 (write reg 20 with 0x5948) 14 - …

Is the what is called VCO_CAPCTRL_STRT in section "7.3.6.1 VCO Calibration" of the data sheet"? I can see no impact of this parameter in the simple layout so is the effect only seen in …

the correct values for VCO_SEL, VCO_CAPCTRL, and VCO_DACISET. These can be read back from the device using rb_VCO_SEL, rb_VCO_CAPCTRL, and rb_VCO_DACISET. If the VCO …

2022年12月23日 · We noticed VCO_CAPCTRL Register Value (R22) is not matching with it's Read Back Register value (R74) for both Auto VCO Calibration (Fcal_En=1) and Forced VCO …

LMX2594/95 application note draft Fast frequency switching using the ^full assist _ mode Multicore VCO integrated PLL+VCO tend to suffer in frequency switching speed with important

capctrl, daciset and vco_sel values are obtained by calibration. Then do a register readback and put these values in a look up table for all the desired frequencies. Next time when you want to …
