Repeaters Assert Triple the Reach of PCI Express Gen-3 Standard

Repeaters for PCIe Gen3National Semiconductor introduced a family of PCI Express (PCIe) Gen-3 (8 Gbps) repeaters that offer desirable signal conditioning performance and low-power consumption for data center servers and storage systems. Powered by the company’s third-generation SiGe BiCMOS process, the new PCIe repeaters address the signal integrity challenges presented by the 8 Gbps Gen-3 data rate. The DS80PCI102, DS80PCI402 and DS80PCI800 provide receive equalization gain up to 36 dB and transmit de-emphasis of 12 dB to deliver 3x the signal reach and half the power (65 mW/channel) of competitive devices, according to the company. The PowerWise repeaters’ performance enables up to 40 inches of FR-4 backplane reach to simplify migration from Gen-2 to Gen-3 data rates, making it possible for system designers to use inexpensive, higher loss cable and board interconnects. The DS80PCI402 enables implementation of x4 PCIe interfaces while the DS80PCI800 is ideal for higher density interfaces such as x8 and x16. The DS80PCI102’s x1 interface is well-suited for industrial and desktop applications. Each device supports seamless detection and management of the new Gen-3 transmit FIR handshake protocol and PCIe out-of-band signals (such as transmit idle/beacon and receive detect) without external system intervention.
