PCB Layout
7.2.10 System Expansion Connector
The system expansion connector is a 128-pin DIN 41612 connector, which provides a
minimal system I/F required to interface to other tool-boards that may use the CPM
expansion connector. This connector contains 16-bit (lower PPC bus) address lines, 16-bit
(higher PPC bus) data lines, plus useful GPCM and UPM control lines.
7.2.11 USB Connector
The USB connectors are standard type-A and type-B USB connectors.
7.2.12 Parallel Port Connector
The parallel connector is a standard 25 pin D-Type male connector.
7.3
The MPC8272ADS layout was done for high-frequency operation and follows the PCI
standard layout recommendations closely. The following list of measures are taken to meet
this design goal:
• Traces as short as possible
• Clock signals and sensitive strobe signals shielded and routed as a chain
• Multilayer PCB with ground and supply layers
• PCI signals lengths and impedance according to PCI standard Rev. 2.2
