These PCB design guidelines are purposefully conservative to minimize potential signal integrity issues. Given this device is targeted for low-cost, handheld application, there is a need to be more aggressive with these best practices. TI highly recommends to perform a full-board-level signal integrity analysis, if these guidelines cannot be followed. The DLPC2607 IBIS models are available for such analysis.
