12 years agoCPLD selection suggestion
Hi, We want to interface two devices (A and B) working at 148.5MHz. The first device (A) gives out data at the negative edge and the second device (B) captures at the positive edge. The cl...

12 years agoAs Tricky and Alex pointed out, I believe the CPLD solution would transfer the timing problem inside the CPLD, with more delays to take into account.
If it's simply a problem of synchronizing / changing the clock edge between device A and B, maybe including a single logic port (buffer or inverter) on the clock line driving one of the devices could make everything working. I don't know your actual design, so maybe this is not feasible in your case, because it arises other timing problems.
