All signals with length matching requirements, MGT and LVDS pairs, must include an
offset to account for the Z-Dok+ propagation delays. The ML410 platforms account for
one-half of the offset, while a user-designed adapter board must account for the other half.
The relative offsets for the ML410 host board PM connector are included in
Users are required to compensate for these offsets when designing adapter boards.

Notes:
1. All offsets are normalized to row F. The ML410 design is based on the data in the Offset/2 column.
PM1 Connector
The PM1 connector provides the following signals:
•
8 RocketIO 3.125 Gb/s transceivers
•
3 LVDS pairs at 2.5V (can be used as 6 single-ended I/O at 2.5V)
•
1 LVDS clock pair at 2.5V
•
12 single- ended I/O at 2.5V
•
26 single-ended I/O at 3.3V
•
1 single-ended clock at 2.5V
•
1 pin not connected
PM2 Connector
The PM2 connector on provides the following signals:
•
39 LVDS pairs at 2.5V (can be used as 78 single-ended I/O at 2.5V)
•
1 single-ended clock at 2.5V
•
1 pin not connected
Adapter Board PM Connectors
Tyco Z-Dok+ adapter board connectors (part number 1367555-1) are the receptacle
connectors on the personality modules that mate to the ML410 host board connectors. See
the
1367555-1 data sheet
On the adapter board connectors, located on the personality module, each signal pair has
a pair of ground pins on the opposite side of the open space, as shown in
page
87. The signal pairs alternate from side to side along the length of the open space. All
of the B and E pins are two contacts tied together and grounded on the personality module.
The A, C, D, and F pins are signal pins.
Difference
F – A = 1513 – 830
F – C = 1513 – 1125
F – D = 1513 – 1219
F – F = 0 – 0
