DS80PCI402SQE/NOPB

PCIE REPEATER/EQUALIZER, 8GBPS, WQFN-54.

The DS80PCI402SQE/NOPB is a 2.5/5/8Gbps 4 Lane PCI Express Repeater with equalization and de-emphasis. The low-power repeater with 4-stage input equalization and an output de-emphasis driver to enhance the reach of PCI-Express serial links in board-to-board or cable interconnects. This device is ideal for x4 (or lower) PCI-Express configuration and it automatically detects and adapts to Gen-1, Gen-2 and Gen-3 data rates for easy system upgrade. DS80PCI402 offers programmable transmit de-emphasis (up to 12dB), transmit VOD (up to 1300mVp-p) and receive equalization (up to 36dB) to enable longer distance transmission in lossy copper cables (10 m or more) or backplanes (40 inches or more) with multiple connectors. The receiver can open an input eye that is completely closed due to inter-symbol interference (ISI) introduced by the interconnect medium.
