1.2.1
Insert the DP PIM board under test into the socket located in the middle of the Digital
Power Development Board. Socket J1 has a slot that defines the DP PIM board
direction. Be careful not to break the slot when inserting the DP PIM board into
the socket.
1.2.2
The Digital Power Development Board ensures good signal integrity and provides
access to all pins of a DP PIM board. Each signal line is named after the DP PIM edge
connector pin number, with a "TP" (Test Point) prefix on the schematic diagram, which
is similarly marked on the silkscreen. These signals are divided into two main sections:
Analog and Digital (see
the DP PIM under test.
1. Analog Section
The analog section is located at the left connector side (smaller sector of the
socket). It consists of 18 signal lines, all referenced to analog ground. These lines
are split into two subsections:
•
•
2. Digital Section
The digital section is located at the right connector side (larger sector of the
socket). It consists of 31 lines, all referenced to digital ground. These lines
support all the digital lines of the DP PIMs. Some of them have dedicated
functions, such as:
•
•
