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.
* Note: In case of obsolescence, the J2 UHM connector will be replaced by the CompactPCI®
2.0 classic J2 connector. This may reduce high speed backplane transfer in particular
applications (PCIe Gen1 2.5GT/s, SATA 1.5Gbps). This does not affect peripherals attached
via the P-HSE mezzanine connector.
The CompactPCI® PlusIO specification refers to SATA data rates of 1.5Gbps and 3Gbps. EKF has
tested successfully also 6Gbps over the backplane with sample devices, but cannot guarantee this
data rate under any conditions. Other devices and other backplane brands/types in use may cause
a different result. Hence, for optimum reliability, the CM238 PCH SATA controller will be initialized
for 3Gbps by default.
Warning: Do not operate the standard PC7-FESTIVAL 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 PC7-FESTIVAL
. For use
together with a 64-bit CompactPCI® classic backplane, special PC7-FESTIVAL 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.
