ENGINEERING NOTES
AZP63
Low Phase Noise Sine Wave CMOS
to LVPECL Buffer/Translator
FUNCTIONALITY
The AZP63 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 AZP63 functional operation.
Figure 2 plots the S-parameters of theD input. S-parameter and IBIS model files for the AZP63 are also available for
download.
