Hi, we use FPGA to generate ONLY ONE external sync clock singal to feed all 15 pcs of EM2120 sync pins on our big power system, connected in daisy-chain topology.
Could you pls tell the SYNC pin's capacitance?
As the output current strength of FPGA pin is about only 4~8mA， we are not should whether it is enough to drive so many sync pins. We need to know the total capacitive load to decide whether a buffer IC should be inserted.
