CompactPCI J2 (PlusIO)
This connector is a high speed UHM connector, suitable for Gigabit Serial I/O. Refer also to PICMG®
2.30 CompactPCI® PlusIO Specification.
Please note, that the CompactPCI® PlusIO specification refers to SATA data rates of 1.5Gbps and
3Gbps. EKF has tested successfully also 6G over the backplane with sample devices, but cannot
guarantee this data rate under any condition. Other devices and other backplane brands/types in use
may cause a different result. Hence, for optimum reliability, the Marvell SATA controller will be
initialized for 3Gbps by default. The J2 backplane SATA 6Gbps configuration would be available
however as a PC6-TANGO option on special request (altered content for the Marvell 88SE9170
attached SPI Flash). EKF recommends that customers validate their particular SATA 6G application
thoroughly, since SATA channel data errors can decrease the performance considerably.
Warning: Do not operate the standard PC6-TANGO in systems with a 64-bit CompactPCI
®
backplane.
The J2/P2 pin assignment of a 64-bit CPCI backplane differs substantially from a CompactPCI
®
PlusIO
backplane, which will result in an overvoltage or short circuit situation on several pins, causing
permanent damage to the PC6-TANGO. For use together with a 64-bit CompactPCI
®
classic
backplane, special PC6-TANGO versions are available on customer request, however supporting only
32-bit peripheral cards. The use of 64-bit CompactPCI
®
classic peripheral boards may cause problems.
