Product Overview

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.
  • Seamless support for Gen-3 transmit FIR handshake
  • Receiver EQ (up to 36dB), transmit de-emphasis (up to 12dB)
  • 0.8 to 1.3Vp-p (pin mode) Adjustable transmit VOD
  • 0.2 UI of Residual deterministic jitter at 8Gbps after 40 inches of FR4 or 10m 30AWG PCIe cable
  • 65mW/Channel Low power dissipation with ability to turn off unused channels
  • Automatic receiver detect (hot-plug)
  • Pins/SMBus/direct-EEPROM load multiple configuration modes
  • ±5kV HBM ESD rating
  • Green product and no Sb/Br
