Hi, How do I use altera pll to generate 32k frequency in cyclone V? I need help for this one. Thanks

Honored Contributor --- Quote Start --- Minimum VCO frequency is 600MHz, so multiply by 4 is too little. --- Quote End --- Ok, so then multiply by 16 (=4*4) to get 800MHz and then divide by 100 (=4*25) to get 8MHz clock, which can then be divided by 250 to get 32KHz. All the multiply / divide counters are 9 bit (range 1..512) on the Cyclone V PLLs per the handbook, so 250 should work just fine.
