Re: [oc] interfacing 16Mhz and I Mhz clock registers

[Umair Farooq Siddiqi <ufarooq.geo@yahoo.com>]

I can adjust skew between two clocks, at present there is no skew between them, 1 Mhz Clock can be considered as 16Mhz clock divided by 16.

 

Thanks

On 16 Mhz side though the clock is at 16 Mhz but data only changes after 16 clocks, hence I am thinking of directly connecting both clock frequency registers. Would you kindly suggest me whether my approach is correct or not? Is there any special care required to meet setup and hold timings ?
