Abstract:
A device is provided that, in one implementation, includes interpolators to generate interpolated phase shifted signals, and a precompensation circuit to provide precompensated versions of data bits in accordance with the interpolated phase shifted signals. Each of the interpolators is assigned a bit pattern different from that assigned to remaining ones of the interpolators.
