Product Overview

IPEX CABLINE®-VS II (20849 Series) is an upgraded version of the popular VESA standard 20455 series. It is fully-shielded with multi-point grounds, which significantly reduces the interference to radio sensitive devices such as antennas, allowing more compact system design.This series is intended for applications demanding next-generation data speeds (for example PCIe Gen5, USB4 Gen4), improved EMC/EMI performance, and robust mechanical performance.

Product Highlight

  • High data-rate transfer up to 40 Gbps / lane
  • Excellent shield with multi-point grounds
  • Simple but reliable mechanical locking cover

Product Lowlight

  • Relatively larger depth
  • Limited popularity and availability
  • The ground points in front of pins limits flexibility of layout on PCB. Pin assignment should be determined with layout in mind.
