Best Practices for Signal Integrity

For best electrical performance and signal integrity of entire system with LMK61XX, TI recommends routing vias into decoupling capacitors and then into the LMK61XX. TI also recommends increasing the via count and width of the traces wherever possible. These steps ensure lowest impedance and shortest path for high frequency current flow. Figure 18 shows the layout recommendation for LMK61XX.
