1Full 2.5 Gbps in each direction, single channel and single channel operation. 2Compatible with multi-channel and multi-channel PCI Express chips. Packetized serial traffic using the PCI Express Split Completion protocol. 3Data Link Layer Cyclic Redundancy Check (CRC) generator and checker, automatic retry of bad packets, integrated low voltage differential drivers, 8b/10b signal encoding. In-band interrupts and messages, support for Message Signal Interrupt (MSI). 4Compliant with the PCI Rev 3.0 standard 32-bit, 66 MHz PCI bus, the PCI host controller allows PCI Express to access PCI target devices. 5The PCI target controller allows full transparent access to PCI Express resources. Allows memory-mapped access to shared RAM and configuration registers. 6An internal PCI arbiter that supports up to four external PCI masters. No drivers are required. 7PM register and PCI backplane PME signal support. Message Signal Interrupt (MSI) support. 8The PEX 8112 PCI Express-to-PCI riser card allows the use of popular PCI chips with high-performance PCI Express networks. 9With the proliferation of PCI Express systems, there are still many applications that do not require the extended bandwidth and performance characteristics of PCI Express. With the PEX 8112, many existing chips and entire subsystems can be used without modification, using a PCI Express motherboard. 10In contrast, the PEX 8112 not only allows full configuration of downstream PCI Express systems from the PCI bus, but also handles limited PCI Express root functions for reverse interrupt and power management events.
