Risetime / falltime 75 picoseconds typical ; Programmable amplitude from 0 to 750 mV. I am using the PL Fabric IO PLL set to 4 MHz, but I get an output of approximately 100 MHz. Programming the internal FPGA allows to set-up the ADC channels and their data read out but also to define logic functions for the I/O ports. This is so fast that, if we were to connect the counter outputs to the 8 on-board LEDs, all the 8 LEDs would seem to be on simultaneously! We need a slow clock! To slow down the input clock, we need a clock divider. However, the reference synthesizer did not produce the correct clock frequency (2^33 mHz or 8. But I want to get 2.
