Hi,

I'd use 0A01 for 2.1GHs.

To chromsoma: Interesting, your PLL-Voltage is out of Specs and about 10% higher than mine. Maybe that's my problem...I'd guess
the to unknown ICs are VR for 5V -> 3.3V and one VR for PLL Voltage. Unfortunately I couldn't read the exact type and for the S1 boards bitmaint seems to have used other types.

Greetings,

You can try to provide PLL voltage externally....
Dont you have regulated power supply?=)

Or maybe you can create 1,1 V from your 5V power supply by building voltage divider;) (If so, then use high values to avoid high current loss)
