Description

System level cost savings tactics are a focus of this board design. Key areas affecting fabrication costs are number of PCB layers and via drill size. The AM570x features a package with via channel arrays. These channels make it possible to build the PCB in only 6-layers while still achieving 100% signal breakout. The added room helps with signal breakout and routing while avoiding the need for smaller: costlier drill bits for the vias. Another added benefit of larger vias is improved via reliability and electrical performance. This reference design is based on the Texas Instruments Sitara™ AM570x System on Chip. The source documents provided represent a board design that’s been tested for stability and compliance in certain key areas. Those areas are DDR stability: HDMI performance: oscilloscope captures of the power sequencing: and a Power Design Network (PDN) Integrity Analysis.
