Communications: Stacked RJ45/USB Connector Reduces PC-Board Footprint

Sept. 20, 2004

The RJ45 2x1 and stacked RJ45/USB integrated connector module (ICM) increases port density and saves pc-board space compared to 1x2 (side-by-side) configurations. Embedded PC applications are the main target for the RJ45 2x1 StackJack (JC0-0019). It sports a local-area network (LAN) port for 10/100/1000BaseTX applications such as LAN-on-Motherboard (LOM) as well as desktop and embedded PCs. The ICM complies with IEEE 802.3i/u/ab and ANSI X3.263 standards, including 350-µH minimum open-circuit inductance (OCL) with 8-mA bias applied. The RJ45 connector meets CAT3/5/5e/6 Fast Ethernet performance requirements and IEEE 802.3 HiPot isolation requirements. Prices start at $7.12 each for quantities of 10,000.
