The ACAP (U1) banks 208/209/210/211 GTM transceivers are split and wired to the QSFPDD1
connector J1 and QSFPDD2 connector J2. The connectors are Molex connector 2147334000
rated at 112 Gb/s per lane.
The transceivers are wired in an opmized paern to allow the QSFPDD1 connector to be
operated at 112 Gb/s per lane and QSFPDD2 can be operated at 56 Gb/s per lane. This
conguraon was chosen to provide 800GAUI-8 funconality. However, while QSFPDD1 is
operang at 800 Gb/s modes, QSFPDD2 cannot be used. To use QSFPDD2, QSFPDD1 is limited
to 56 Gb/s. This allows for both connectors to be operated simultaneously at 400GAUI-8 or
similar modes.
For connecvity details, see the table in the Transceivers secon and schemac page 57. See the
Versal ACAP GTM Transceivers Architecture Manual (AM017) for more details on 112 Gb/s GTM-
Quad conguraons.

[Figure 3, le callout 14]
The ACAP (U1) banks 121/122/123/124 GTM transceivers are wired to the QSFPDD5
connector J359. The ACAP (U1) banks 221/222/223/224 GTM transceivers are wired to the
QSFPDD6 connector J358. The connectors are Molex connector 2147334000, rated at 112
Gb/s per lane.
The transceivers are wired in an opmized paern to be operated at 112 Gb/s per lane. This
