9. APPLICATION INFORMATION
The recommended schematic, component placement, and PCB layout for a single-
sided DIP design are provided in the following figures. I²C communication and
XTAL mode are chosen in the reference circuit design. EMI and noise in the video
frequency range is kept to an absolute minimum by running the ground plane
underneath the entire Z86230 package length. This design is recommended for
both SOIC and DIP package styles.
