8 Channel PCI Express Repeater

8 Channel PCI Express Repeater

The DS80PCI800 is a low power, 8 channel repeater with 4-stage input equalization, and output de-emphasis driver to enhance the reach of PCI express serial links in board-to-board or cable interconnects. Ideal for higher density x8 and x16 PCI express configurations, the DS80PCI800 automatically detects and adapts to Gen-1, Gen-2 and Gen-3 data rates for easy system upgrade.

Each channel supports seamless detection and management of the new Gen-3 transmit equalizer coefficients (FIR tap) handshake protocol and PCIe control signals such as transmit idle, beacon etc. without external system intervention. An automatic receive detection circuitry controls the input termination impedance based upon endpoint insertion (hot-plug events).
