10 Industrial Design
The recommendations below are aimed at improving the system ESD performance.
11 2-Layer Escape Routing Example
The i.MX283 family member feature set and pinout is optimized to allow for 2 layer escape routing using
PCB industry standard 5 mil trace/space and 8/16 through-hole vias. This will also allow for 4 layer PCB
designs in most cases depending on other board peripherals. The example layout below shows a 2 layer
escape route. The Allegro source layout file for this escape route is available for download from the
Freescale i.MX28 support web page.

It is preferred that ferrite beads should have a minimum impedance of 500 ohms @ 100MHz with
the exception of the ferrite on USB_5V.
Buttons or switches on the housing should be non-conductive.
The USB jack should be covered by a non-conductive case or rubber plug.
If metal or conductive player housings are used, they should be designed to allow equal charge
distribution on all sides of the PCB.
Air gaps between buttons and the housing should be kept as small as possible.
