DESCRIPTION  
The DS80PCI800 is a low power, 8 channel repeater with 4-stage input equalization, and output de-emphasis  
driver to enhance the reach of PCI express serial links in board-to-board or cable interconnects. Ideal for higher  
density x8 and x16 PCI express configurations, the DS80PCI800 automatically detects and adapts to Gen-1,  
Gen-2 and Gen-3 data rates for easy system upgrade.  
Each channel supports seamless detection and management of the new Gen-3 transmit equalizer coefficients  
(FIR tap) handshake protocol and PCIe control signals such as transmit idle, beacon etc. without external system  
intervention. An automatic receive detection circuitry controls the input termination impedance based upon  
endpoint insertion (hot-plug events). These features guarantee PCIe interoperability at both the electrical and  
system level, while reducing design complexity.  
Powered by National’s SiGe BiCMOS process, 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 (10m+), or backplanes (40”+) with multiple connectors. The receiver is  
capable of opening 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 via pins, software (SMBus/I2C) or loaded via 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.  
With a low power consumption and control to turn-off unused channels, the DS80PCI800 is part of National's  
PowerWise family of energy efficient devices.
