PRODUCTION DATA.
Upon every frequency change, before the FCAL_EN bit is checked, the user provides a good estimate of the initial starting point for the VCO core (VCO_SEL), band (VCO_CAPCTRL_STRT), and amplitude (VCO_DACISET_STRT). To do the partial assist for the VCO calibration, follow this procedure:
VCO CORE | fMin (MHz) | fMax (MHz) | CMin | CMax | AMin | AMax |
---|---|---|---|---|---|---|
VCO1 | 3200 | 3650 | 131 | 19 | 138 | 137 |
VCO2 | 3650 | 4200 | 143 | 25 | 162 | 142 |
VCO3 | 4200 | 4650 | 135 | 34 | 126 | 114 |
VCO4 | 4650 | 5200 | 136 | 25 | 195 | 172 |
VCO5 | 5200 | 5750 | 133 | 20 | 190 | 163 |
VCO6 | 5750 | 6400 | 151 | 27 | 256 | 204 |
