It is critical for today’s networks to maintain
maximum reliability and uptime. Overvoltage surges caused by indirect lightning,
power line transients, and ESD can wreak havoc on a network that is not properly
protected. Short circuit and overload conditions can cause safety issues for the
equipment and the users. With some simple design considerations for protecting
network and telecommunications ports, the equipment makers can ensure that
application standards are met and equipment is protected against these types of
faults. Proper fuse and PTC selection as well as selecting the optimal TVS Array
will be discussed. High speed networks now require TVS diode arrays with
ultra-low capacitance, high surge capability, and very fast clamping speed. Low
dynamic resistance of these TVS diode arrays become more critical as PHY
chipsets are inherently very weak to surge and ESD events.

attendees will learn:

  • Identify pertinent standards and/or regulatory requirements for network
  • PCB Layout Rules for optimal circuit protection
  • Signal Integrity/Capacitance Budget considerations when selecting protection
  • Overcurrent protection selection methods for Data lines and PoE.
  • Overvoltage (ESD and Lightning) protection selection methods for datalines,
    PoE, and Power Ports

Who should attend:

  • Design Development Engineer (Software or Hardware)
  • Design/Development Engineering Manager (Software or Hardware)
  • Other Engineering
