Pixel Protocol Overview: WS2801

This pixel protocol was designed by World Semi in China. WS2801 offers many of the benefits the WS28xx series is famous for, plus the addition of a clock line to allow refresh rates to be much higher. The control circuit comes in a SOP14 package, allowing for more flexibility with LED choice.
