Hi all, I have a Altera Cyclone chip which is input by a 50MHz osc. I want to use this 50MHz clock directly without PLL. This means I just use a clk as input and assign the PIN GCLK to clk. Is it OK? Thanks in advance. ABAI
Can Altera Cyclone device's clock input directly used as CLK with PLL?

No problem.. Using PLL is optional.. If you have a doubt yet, use PLL with 1x, 1 div. setting. (P.S In subject.. with-> without.. Am I right?)

Just make sure that you tie the osc to one of the clock pins that drives into the global clock network.
