Original question:

thanks
Hi Cannie,
I would use the DS125DF1610 ability to internally invert channel polarity as necessary to help improve the escape routing as shown in the attached picture.
The DS125DF1610 uses a 3-tap FIR filter to assist with transmit equalization. The FIR filter consists of a pre-cursor tap, a main cursor tap and a post cursor tap. Each tap has a polarity bit and 64 available levels. By default, the main cursor tap is set to a positive polarity, while the pre cursor and post cursor taps are set to anegative polarity. Users can invert the polarity of all 3 FIR taps to invert the polarity of the output data.
Regards,
Lee
