EM2120L01QI SYNC pin's capacitance

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.

close it. 10pF around.

and EM2120 sync function is OFF by default, need to be Enabled by I2C bus......
