dedicated wire needed only for the strobe input. In a micro-
processor–controlled system this strobe input is accessed
when the phase lock loop is addressed. The remaining data
and address inputs will directly interface to the microproces-
sor’s data and address buses.
integer reference divide value between 3 and 4095. The wide
selection of ÷R values permits a high degree of flexibility in
choosing the reference oscillator frequency. As a result the
reference oscillator can frequently be chosen to serve multi-
ple system functions such as a second local oscillator in a
receiver design or a microprocessor system clock. Typical
applications that take advantage of these ML145146 features
including the dual modulus capability are shown in Figures
12, 13 and 14.
