The internal clock circuit is completed with the
addition of an external 3.579545 MHz crystal and is
connected as shown in Figure 6 (Single-ended Input
Configuration).
Applications
A single-ended input configuration is shown in Figure
6. For applications with differential signal inputs the
circuit shown in Figure 5 may be used.
