CXA2674EM |
|
The CXA2674EM is a photodetector IC (PDIC) that detects both RF and servo signals and mounted in a record/playback optical pickup that supports the blue-violet laser diode used for Blu-ray and other optical discs. This device is fabricated in a leading-edge process that improves the optoelectronic conversion characteristics in the blue-violet wavelength range to almost the theoretical limits. It also achieves a high signal-to-noise ratio by including a low-noise amplifier. This device features a standby mode function that allows power consumption to be minimized when the device is not being operated. (Operating mode: 30 mA, standby mode: 2 mA) This product is provided in a newly-developed package that is appropriate for photodetection in the wavelength range of the blue-violet laser. |

CXA2673EM |
|
The CXA2673EM is a photodetector IC (PDIC) developed for use as a laser power monitor and mounted in a record/playback optical pickup that uses the blue-violet laser diode used for Blu-ray and other optical discs. This device adopts the same leading-edge process used for the CXA2674EM and the same package. It provides excellent performance as a front monitor for blue-violet laser diodes. |

Newly-Developed Package for Blue-Violet Laser Diodes |
|
Sony has developed a new cavity mold glass sealed package for blue-violet laser diodes. Conventional transparent plastic packages have low transparency in the wavelength range of the blue-violet laser diode, and furthermore, it has been shown that long-term exposure to blue-violet laser diode light degrades plastic package material. Therefore, Sony developed this new package that mounts the silicon chips in a molded cavity area and seals them in that area with glass that has antireflection coating on both sides, thus resolving both these problems. |

The Industry's Smallest
GPS Module Developed |
|
Sony has now developed the
industry's smallest surface mounting GPS module with
a mounting area of only 322 mm2
. Sony is also proceeding with the development of a
QS9000 conforming automotive module as well to respond
to a wide range of user needs. |

No rose without a thorn. While
the blue laser diode was a miraculous development, and
it is an extremely attractive device, it was not easy
to develop a PDIC that could receive that light. Revising
the fabrication process was, of course, necessary, and
we even developed a new package in creating this new
product! This is a very friendly product and can be
used by almost anyone. It's good to be able to relax
again now that this project is done. |
