PI3EQX10908
10.0Gbps 8-Channel PCIe ReDriver™with Pinstrap and I
2
C Control
and FlowThrough Pinout
Pericom Semiconductor’s PI3EQX10908 is a lower power,
high performance 8-differential channels PCIe ReDriver™.
The device provides per channel programmable equalization,
output swing, de-emphasis, and amplifier gain.
The PI3EQX10908 provides master/slave I
2
C Control, to
optimize performance over a variety of physical mediums by
reducing Inter-symbol interference.
PI3EQX10908 supports eight 100-Ohm Differential data
I/O’s and extends the signals across other distant data
pathways on the user’s platform.
Pericom PI3EQX10908 offers programmable transmit de-
emphasis (up to 9 dB), transmit V
OD
(up to 1200 mVp-p) and
receive equalization (up to 35.7 dB) to enable longer distrance
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 (I
2
C) 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.
