BUS ADDRESS SELECTION
The device address contains programmable address bits MA1 and MA0, which offer the possibility of having up to four
MOPLL ICs in one system. Table 5 gives the relationship between the voltage applied to the AS input and the MA1 and
MA0 bits.

test/AGC bit
T/A = 0: the next six bits sent are AGC settings
T/A = 1: the next six bits sent are test and reference divider ratio settings
test bits; see Table 6
reference divider ratio and programmable frequency step; see Table 7
AGC current setting and time constant; capacitor on pin AGC = 150 nF
ATC = 0: AGC current = 220 nA; AGC time constant = 2 s
ATC = 1: AGC current = 9
