CXA2677GA - (CXA2676GA / CXA2677GA) Optical Pickup Chipset

Download the CXA2677GA datasheet PDF. This datasheet also covers the CXA2676GA variant, as both devices belong to the same (cxa2676ga / cxa2677ga) optical pickup chipset family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • two additional pins: WPP1 (A + B) and WPP2 (C + D). This allows the generation of the WRF signal used in earlier (CXA2660N) CD-R/RW systems with the WPP1 + WPP2 signal and the detection of address bit signal unique to DVD ±R/RW with the WPP1.
  • WPP2 signal. Also, it adopts a three-stage structure with a write mode and two read modes with high gain and low gain mode settings. The band limiter function used in write mode provides an average value signal with high precision. LGA COB (chip.

Optical Pickup Chipset with CD/DVD Recording Photodetector IC (PDIC) Supports High-Speed Writing to both CD and DVD Media CXA2677GA CXA2676GA 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.
