The CXA2702GA is a photodetector IC (PDIC) that was developed as the photodetector for optical pickups used in DVD R/RW recording drives. Like the earlier x8-speed CXA2677GA, it provides the WPP1 and WPP2 signals that are optimal for address pit signal detection. In increasing the recording speed to x16, Sony added a 3x gain switching function to WPP1 and WPP2. The new IC thus has an additional 2 bits of control compared to the earlier gain switching system. The CXA2702GA also now provides an input pin that can control the output limiter volt-
