Re: Soekris Dam Dac

Also, check out u2 on the 1121, between u8 and u11 f-f, it’s a lvds to ttl converter like DS90LV012A, where pin 5 is terminated then distributed to f-f and fpga.

Re: Soekris Dam Dac

Re: Soekris Dam Dac

Hello everyone, I want to make the 1.2 and 3.3 ldo upgrade on my dam1121. If i remove the stock regulators, it is correct to tap at the marked points to supply the board with 1.2 and 3.3v?
