Welcome to the store! 1、Full 2.5 Gbps in each direction, single-channel and single-channel operation. 2、Compatible with multi-channel and multi-channel PCI Express chips. Packaged serial traffic with the PCI Express Split Completion protocol. 3、Data Link Layer Cyclic Redundancy Check (CRC) generator and checker, automatic retry of bad packets, integrated low-voltage differential drivers, 8b/10b signal coding. In-band interrupts and messages, support for Message Signal Interrupt (MSI). 4、Compatible with PCI Rev 3.0 standard 32-bit, 66 MHz PCI bus, the PCI host controller allows PCI Express to access PCI target devices. 5、The PCI target controller allows complete transparent access to PCI Express resources. Allows memory-mapped access to shared RAM and configuration registers. 6、An internal PCI arbiter that supports up to four external PCI masters. No drivers required. 7、PM registers and PCI backplane PME# signal support. Message Signal Interrupt (MSI) support. 8、The PEX 8112 PCI Express-to-PCI riser card enables the use of popular PCI chips with high-performance PCI Express networks. 9、With 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 PEX 8112, many existing chips and entire subsystems can be used without modification, with a PCI Express motherboard. 10、In contrast, the PEX 8112 not only allows complete 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.
