86 / 107 page ![]() ATF280F [DATASHEET] 7750E −AERO−05/12 86 15.2 Pin Assignment The core of the FPGA is supplied through VDD pins that are linked all together in a dedicated power cluster. The ATF280F periphery is divided into 12 clusters. Eight clusters are dedicated to programmable I/Os and four clusters are dedicated to LVDS. Each cluster consists in a set of I/O together with its dedicated power supply source. The following tables summarized the pin assignment cluster by cluster. The ground planes between core and periphery are linked together and are described as a “Gnd” cluster. 15.2.1 Core Power and Ground Cluster Table 15-3.
