My customer is using only IF1P/N.
So VCS2, IF2P/N, VBIASIF2, VGATE2, RF2, LOBIAS2, and RSV are all floated.
However, PLL is not locked.During debugging, when power is applied to VCC2, PLL lock is said to be locked.
On the block diagram, VCO is expressed as one, but the power is divided into VCC1 and VCC2.
Is it correct to supply power for both?
please answer about my question.
As you can see in Pin Description on page 20 and Table 2 on page 3, VCC2 is also VCO Supply voltage as well as VCC1. So 5V nominal voltage should be applied to VCC2 Pin.
