PRODUCTION DATA
This option works only in conjunction with the 2-pixel/clock mode (PIXS = high). Setting STAG = low time-staggers the even- and odd-pixel outputs so as to reduce the amount of instantaneous current surge from the power supply. Depending on the PCB layout and design, this can help reduce the amount of system ground bounce and power-supply noise. The time stagger is such that in 2-pixel/clock mode, the even pixel is delayed from the latching edge of ODCK by 0.25 tcip. (tcip is the period of ODCK. The ODCK period is 2 tpix when in 2-pixel/clock mode).
Depending on system constraints of output load, pixel rate, panel input architecture, and board cost, the TFP401/401A drive-strength and staggered-pixel options allow flexibility to reduce system power-supply noise, ground bounce, and EMI.
