    Magnetics in Ethernet connected devices

    I am about to make a schematics for ethernet switch and processor. I am using Ethernet switch IC which has 5 ports one port is connected to processor's buit-in phy. so I only left with 4 ports which are connected to ethernet devices that are present on same board. I want to know that is it fine...

    [SOLVED] DDR3L SDRAM Capacity Calculations

    Hi, I need to know by which techniques I can calculate chip capacity. I actually not understand by a sample board available to me. it has 4 SDRAM chips 2 on bottom and 2 on top total capacity is 2GB available But when I look to datasheet of SDRAM I was unable to calculate. Datasheet link: Page...

    Trace Spacing in high speed PCB DDR3L routing

    Hi, I am working on high-speed PCB and I am new in this field. According to design routing guide I need to know what is trace 3x units Dielectric actually means It is spacing from other signals but I am confused in 3x Please se the attached photo
