PI3EQX10908A
10Gbps 8-channel 10GE, ReDriver™with Linear Equalization
Description
Pericom Semiconductor’s PI3EQX10908A is a 10 Gigabit
Ethernet, 8 differential channels ReDriver™. The device pro-
vides programmable linear equalization, output swing and
flat gain, by either pin strapping option or I2C Control, to
optimize performance over a variety of physical mediums by
reducing Inter-symbol interference.
PI3EQX10908A supports four 100-Ohm Differential CML
data I/O’s and extends the signals across other distant data
pathways on the user’s platform.
The integrated equalization circuitry provides flexibility with
signal integrity of the signal before the ReDriver, whereas the
integrated circuitry provides flexibility with signal integrity of
the signal after the ReDriver.
