    The schematic looks fine.

    I would suggest to place 1n capacitors from pin 2,3,4,5 to ground. These can be a do not mount and can be used if system noise needs to be decoupled.

    Hi Sanjay,

    X+/X-/Y+/Y- Is there any line width requirement for this group of lines?
    The current path is 10mil, the line length is as shown below, and the adjacent layer is the GND layer.
    GND will be laid around TCA2007.

    Sometimes the Electronics of a touch Panel is packed very tightly with the electronics of a display. Switching Waveforms might couple into the X+/X-/Y+/Y- Lines. The Ground adjacent to the traces and the ground layer below are a good idea to shield the traces. Would it be a possibility to plave the lines in an inner layer such that there are ground planes above and below ? This would result in the Traces perfectly shielded.
