The AZP51 is one of a family of parts that provide options of fixed ÷1, fixed ÷2 and selectable ÷1, ÷2 modes as well as

active high enable or active low enable to oscillator designers. Table 2 details the differences between the parts to assist

designers in selecting the optimal part for their design.

Table 3 lists the specific AZP51 functional operation.

Figure 2 plots the S-parameters of the D input. S-parameter and IBIS model files for the AZP51 are also available for

download.
