Routing DDR3 Memory and CPU fan-out
By a bit of care and planning ahead, routing and length tuning DDR3 fanouts can be a stress-free process,
even on the most compact and densely packed designs.

Con un poco de cuidado y planificación, el rutado y la afinación de longitud de fanouts DDR3 puede ser un proceso sin complicaciones, incluso en los diseños más compactos y densos.

How to Route DDR3 Memory and CPU fan-out It's becoming more and more inevitable that board designers have to do High edge rate (high speed) PCB designs when working with microcontrollers. With the power of CPU's like the Freescale iMX6 multi-core ARM device family, but at very low "cost per MIP", it's more and more desireable to use device...
