Diodes’ PI3HDX12211A is a multi-data rate, 4 differential chan-

nels ReDriver™. The device provides 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.

PI3HDX12211A supports four 100Ω 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 linear amplifier/buffer circuitry provides flexibility

with signal integrity of the signal after the ReDriver. The chip

provides low equalizer options for short prechannel.
