Srdjan,
Ok, I see now. Thanks for the explanation!
I have a couple more questions about the values for the chip init
sequence we use - in the next e-mail.

Alexander,
VCOREG is in fact on chip LDO which takes 3.3V and generates 1.8V for VCOs
supply. However, we do not recommend internal VCO 1.8V regulators to be used
as they are more noisy than the external ones. Hence, by default internal
regulators are powered down and bypassed so clean external 1.8V can be
supplied via the chip pins.

Hi guys,
Could anyone tell me, the software guy, what may be the purpose of
VCOREG block in LMS6002D (Figure 3.4 at the Programming Guide)? In our
current code it's always powered down and not used, and I just wonder
whether it could be used for frequency hopping and what are other
potential uses. If I understand correctly, it's a kind of fine tuning
for the PLL output frequency.
