14 years agoI'm not sure how different the ALT2GX component is relative to the Stratix IV GX ALTGX components, however, the following application note is pretty good:
http://www.altera.com/literature/an/an553.pdf The cal_blk_clk on the Stratix IV has its timing requirements specified in the handbook, so the Stratix II GX should have it specified too. Something around 50MHz should be fine. Cheers, Dave
