Standart quartz oscillator

i connect standart oscillator ALTUFM_OSC osc( .oscena(1'b1), .osc(clk)) 

i count 6 000 000 by counter.  

begin counter = counter+ 1'b1; if(counter == const_data) begin signal = ~signal; counter = 25'b0; end  

LED blinks once per second. 

Is it means, that frequency of quartz oscillator is 6MHz (instead of 50MHz)?

Seems to fit well the ALTUFM user guide. Did you ever looked into it? The MAX II/V internal oscillator is no quartz oscillator, btw.
