DS80PCI402
PRODUCT BRIEF 2.5 Gbps / 5.0 Gbps / 8.0 Gbps 4 Lane PCI
Express
Repeater with Equalization and De-Emphasis
General Description
The DS80PCI402 is a low power, 4 lane 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 x4 (or lower) PCI express configuration, the DS80PCI402 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, DS80PCI402
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.
