www.DataSheet4U.com Optical Pickup Chipset with Photodetector ICs Supports High-Speed Writing to CD and DVD CXA2702GA/CXA2716GA/CXA2701GA Although it has only been a year since Sony released the CXA2676GA and CXA2677GA* for DVD ×8-speed recording, DVD recording speed has already reached ×16. Sony’s newly-developed CXA2701GA and CXA2702GA/ CXA2716GA optical pickup photodetector ICs (PDICs) support this ×16 record speed. *: See CX-News, Volume 32, for details on the CXA2676GA and CXA2677GA.

Like the earlier ×8-speed CXA2677GA, it provides the WPP1 and WPP2 signals that are optimal for address pit signal detection. In increasing the recording speed to ×16, Sony added a 3× 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 ...
