AM CP
AM charge
pump output
Charge pump output for AM
Serial data input:
When AM / FM = "1" error output
from the phase comparator is output
as constant current.

: (+) current output
Serial data:
Output current can be switched using
CR0 and CR1 bits.
Normally (when using AM op
amp), set
the OP SEL bit to "1".
