BIT | FIELD | TYPE | RESET | DESCRIPTION |
---|---|---|---|---|
15-6 | R/W | 8h | Program 8h to this field. | |
5 | EXTVCO_CP_POL | R/W | 0h | Sets the phase
detector polarity for external VCO in PLL mode operation.
Positive means VCO frequency increases directly proportional to
Vtune voltage. |
4-0 | EXTVCO_CP_IDN | R/W | 10h | Set the base
charge pump current for external VCO in PLL mode operation. The
total base charge pump current is equal to EXTVCO_CP_IDN +
EXTVCO_CP_IUP. EXTVCO_CP_IDN must be equal to EXTVCO_CP_IUP.
Only even number values are supported. |
