GTM214/215/216/217: OSFP
[Figure 3, callout 55]
The ACAP (U1) banks 214/215/216/217 GTM transceivers are wired to the QSFPDD6
connector J362. The connector is TE connecvity connector 2344064-4, 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
conguraon was chosen to provide 800GAUI-8 funconality.
For connecvity details, see the table in the Transceivers secon and schemac page 60. See the
Versal ACAP GTM Transceivers Architecture Manual (AM017) for more details on GTM-Quad
conguraons.
GTM219: SMA/1588 PPS
[Figure 3, callout 41]
The ACAP (U1) bank 219 GTM transceivers are wired to the SMA connectors J373, J374, J375,
and J376. The connectors are the Carlisle SMA TMB-V5F2-3L1, rated at 34 GHz. The remainder
of the ACAP (U1) bank 219 GTM transceivers are wired to the Renesas 8A34001 system
synchronizer (U219). This provides for an IEEE 1588 PPS signal. This is intended to be coupled
with REFCLK0, which has been ed to an output from the Renesas 8A34001 (U219) system
synchronizer for IEEE 1588 use.
The transceivers are wired in an opmized paern to be operated at 112 Gb/s per lane. This
conguraon was chosen to provide exibility for evaluaon of GTM transceivers.
For connecvity details, see the table in the Transceivers secon and schemac page 18. See the
Versal ACAP GTM Transceivers Architecture Manual (AM017) for more details on GTM-Quad
conguraons.
QSFP-DD Control Signals
The QSFP-DD control signals can be asserted in mulple ways. Each QSFP-DD has an I2C
connecon to the I2C1 bus through the I2C mulplexer (TCA9548PWR U35) as shown in the
PMC MIO[44:45] I2C1 Bus secon.
The following table lists the transceiver module control signals.
