产品概述
The DS80PCI800 is a low-power, 8-channel 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 higher density x8 and x16 PCI-Express configurations,
and it automatically detects and adapts to Gen-1, Gen-2, and Gen-3 data rates for easy system
upgrade.DS80PCI800 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.
