I have had EMI problems in the past and I have decided to implement clock distribution with termination.
I have a 25 MHz crystal that travels through a 50 \$\Omega\$ strip in the PCB and splits into two. After the split the strips have an impedance of 100 \$\Omega\$. Each strip goes to an IC and then is terminated with a 100 \$\Omega\$ resistor to ground. I copied the idea from a book. (High speed digital design. A handbook of black magic)
When I turn on the board, I noticed the ICs don't operate well as they miss clocks. When I remove the terminating resistors all is ok. I am trying to do a good job to prevent problems with EMI.
What am I missing?
