PlusIO
CompactPCI® PlusIO (PICMG® 2.30) is a standard for rear I/O across J2. High speed signal lines (PCI
Express®, SATA, Gigabit Ethernet and USB) are passed from the PC3-ALLEGRO through the special
UHM J2 connector to the backplane, for usage either with a PlusIO rear I/O transition module, or
CompactPCI® Serial card slots.
CompactPCI® Serial (PICMG® CPCIS.0) defines a completely new card slot, based on PCI Express®,
SATA, Gigabit Ethernet and USB serial data lines. On a hybrid backplane, both card styles can reside,
CompactPCI® and CompactPCI® Serial, with the PC3-ALLEGRO in the middle as controller for both
backplane segments.
The PC3-ALLEGRO can be used in any system with a CompactPCI
®
PlusIO backplane according to the
PICMG
®
2.30 specification. Hybrid backplanes allow the configuration of systems with CompactPCI
®
Serial slots in addition to classic CompactPCI
®
boards.
