MA1, MA0

programmable address bits (see Table 6)

N14 to N0

programmable divider bits; N = N14

CP

charge pump current:

CP =0=60

µA

CP = 1 = 280

µA (default)

T2, T1,T0

test bits (see Table 7)

RSA, RSB

reference divider ratio select bits (see Table 8)

OS

tuning amplifier control bit:

OS = 0; normal operation; tuning voltage is ‘ON’ (default)

OS = 1; tuning voltage is ‘OFF’ (high-impedance)

PVHFL, PVHFH, PUHF, FMST

PNP ports control bits:

bit = 0; buffer n is ‘OFF’ (default)

bit = 1; buffer n is ‘ON’
