The AD9364 Reference Manual, UG-673, says that the BB PLL charge pump has "programmable output current from 25 μA to 1575 μA in 25 μA steps. In addition, a programmable bleed current is available. This is an NMOS current source programmable from 0 μA to 316 μA" (see page 20). However, in looking at the BBPLL control registers in the AD9364 Register Map Manual, UG672, there doesn't seem to be a way to set the bleed current. Only one register (0x46) is labeled as Charge Pump Current; this is presumably not for bleed current, or is it?
Is there a way to set BBPLL bleed current, and if so, how?
(The same is true for the AD9361 -- there doesn't seem to be a way to set the BBPLL bleed current.)
