Cyclone II FPGA Clock Selection

Time to take a look at clocks, and what exactly we need for the Cyclone II FPGA. I’ve spent considerable time digging around in different corners of the internet trying to find good advice on selecting a clock for my FPGA without much luck. So, I decided to get my hands dirty and figure it [ READ MORE ]

Cyclone II Voltage Regulators

I decided to interrupt my Cyclone II Handbook dissection series in order to build the voltage regulators needed for the Saturn Project. The EP2C8 Cyclone II FPGA we have on our breakout board requires nine voltage supplies: Voltage Supply Name Description Voltage Level VCCINT These are internal logic array voltage supply pins. VCCINT also supplies [ READ MORE ]

Dissecting the Altera Cyclone II Handbook – Part 2

Welcome back to the second part of the series dissecting the Altera Cyclone II Handbook. I’m ripping out all of the important information you need to know from the 470 page tome, and condensing it down to a couple of blog posts. This week I’m going to take a look at the clocks and PLL [ READ MORE ]
