Clock Pins for Arria 10 SoC Development Kit

Hello,

I am looking at the pinout pdf file for the Arria 10 SoC Development Kit, and so far it just looks like an alien language.

I am just looking for a pin that I can use in my FPGA Verilog design that has more than 135 MHz.

I am using the kit with the fmcdaq2 board and in the example project there is 333.333MHz clock (tx_ref_clk) that is connected to PIN_N29 (and there is also "tx_ref_clk(n)" connected to PIN_N28 for some reason), but even though I use this clock, my design doesn't work properly. I believe this clock signal changes and is not actually continuously 333.333MHz, so that is why it is not working. Is there any pin that I can use in my design that has a clock of at least 135 Mhz? (I can use Altera IOPLL IP to choose my desired clock, so I would appreciate it if the frequency is much higher)
