Control and Acquisition Signals Headers J10 and J20
J20 is a 2x20 pin 0.1" pitch pin header which provides buffered control signals to an external controller (such as
J10 provides direct connection to the HPC1-FMC (FPGA Mezzanine Card) connectors on the
. Table 14 below shows the FPGA pin routing for each LX7720 pin on these kits.
