CXA2677GA |
|
The CXA2677GA is a photodetector
IC (PDIC) that was developed as the photodetector element
for optical pickups used in DVD ±R/RW drives. It 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. |

The CXA2676GA adopts a two-channel
structure to allow the power of the CD laser and the
DVD laser to be set individually. It achieves fast response
characteristics, namely a slew rate of 250 V/us and
a settling time of 7 ns. These characteristics are adequate
to support write speeds of x52 for CD-R and x8 for DVD-R. |

LGA COB (chip on board) Small Package |
|
To increase the number of
pins while retaining the package dimensions (4.5 x 3.2
mm) of the earlier chip on board (COB) package, Sony
developed a new land grid array (LGA) package that positions
the contacts in a two-di mensional array on the reverse
side of the package. This allows these devices to provide
increased functionality without increasing the mounting
area. This package is optimal for developing ultrathin
pickups, that is, pickups for use in 9.5 mm ultrathin
drives. |

Despite our busy schedule, we are confident that we succeeded in responding to our customers' input to the greatest extent possible in the development of these new products. Even though the design period was short, we put careful detailed attention into every single element in these products. We are sure our customers will be fully satisfied. It's good to be able to relax again now that this project is done. |
