3.7 Synchronizing Multiple Modules
The PCIe-9852 provides a dedicated connector as system syn-
chronization interface, enabling multiple module synchroniza-
tion. As shown, bi-directional SSI I/Os provides a flexible
connection between modules, allowing one SSI master PCIe-9852
to output SSI signals to other slave modules. The table summa-
rizes SSI timing signals and functionalities.
All SSI signals are routed to the 16-pin connector from
FPGA, enabling multi-module synchronization. ACL-eSSI-2/
