Clock Divider by 256
Clock Divider by 256
(OP)
Hello,
I want to divide 8Mhz clock to 31.25Khz. So I guess I need a divider by 256 IC. I haven't worked with digital logic for so long now and I can't remember which IC does this. Would you please suggest which part I can use? Thanks!
Best regards,

Use a counter on a micro.

31.25 sounds vaguely like a video application, so there may already be video chips that do that

Even in this VHDL world, I think 'they' still make them.

minimum max operating frequency 24 MHz @ Vcc=4.5
minimum max operating frequency 28 MHz @ Vcc=6.0
both over Tamb -40 ~ +85 C.
Typical max operating frequencies @ 25C are 82 @Vcc=4.5
90 MHz Vcc=2, and 98 MHz @ Vcc=6.
Great 4xxx series functionality in the peppy 74HC family!
