10.5.1 Interlock
An interlock mechanism is implemented on the SIS8300-KU for operation with Vectormodu-
lator cards like the DWC8VM1 and DS8VM1. The OUT0 and OUT1 Zone 3 signals are
generated from the logical combination of the backplane signals TX_19 (RF permit), RX_20
(RF gate) and the FPGA ILOCK signals.
The interlock scheme is shown in the diagram (courtesy of DESY) below.
