The signal processing required for DVD is far more complex than that for CD.
Sony has now developed an optical pickup chipset, the CXA2677GA and CXA2676GA, that is appropriate for this complex signal processing.
These devices adopt a newly-developed LGA type small package and can contribute to the development of ultrathin pickups.

CXA2677GA
RF/Servo PDIC
■ Supports high-speed CD/DVD write operations (CD-R: ×52-speed, DVD-R: ×8-speed)
■ WPP1 (A + B) and WPP2 (C + D) outputs, which are optimal for DVD address bit detection
■ Band limiter function for write operations
■ Eight-section photodiode for DPP
■ 16-pin LGA COB small package

CXA2676GA
Laser front monitor PDIC
■ Two-channel structure (Vin1, Vin2)
■ Chip capacitors (1005) included
■ 8-pin LGA COB small package
