The DS80PCI102 is a low-power, 1-lane 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. The device is ideal for x1 PCI-Express configuration, and it automatically detects and adapts to Gen-1, Gen-2, and Gen-3 data rates for easy system upgrade.

DS80PCI102 offers programmable transmit de-emphasis (up to 12 dB), transmit VOD (up to 1300 mVp-p), and receive equalization (up to 36 dB) to enable longer distance transmission in lossy copper cables (10 meters 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.

The programmable settings can be applied easily through pins or software (SMBus/I2C), or can be loaded through an external EEPROM. When operating in the EEPROM mode, the configuration information is automatically loaded on power up, which eliminates the need for an external microprocessor or software driver.
