Carrier board design guidelinesEdit
This page provides general guidelines about how to implement carrier boards hosting SOM.
In the following sections further hardware guidelines valid for Maya are illustrated. The information provided here complete the Carrier board design guidelines for some specific interfaces.
Interfaces GuidelinesEdit
For interfaces not mentioned in this section, refer to the generic guidelines.
USBEdit
PCBEdit
Table listeb below integrated the general basic guidelines table
| Parameter for USB Differential Pairs | Min | Typ | Max |
| Max traces length | - | - | 17" |
LCD InterfaceEdit
PCBEdit
- Matching depends from Pixel Clock. As general rule, match lines at 500-800 mils
- Place series terminator near Maya Connector
VIN InterfaceEdit
PCBEdit
- Matching depends from Pixel Clock. As general rule, match lines at 500-800 mils
- Place series terminator near VIN source
RMII InterfaceEdit
SchematicEdit
- use a standard RMII PHY device that support 50MHz Clock input mode
- Set PHY address different from integrated PHY
