| STV5805 PHOTO DETECTOR FOR DIGITAL VIDEO DISK . . . PRELIMINARY DATA LARGE BANDWIDTH (30MHz) AND LOW NOISE I/U AMPLIFIER SENSITIVITY SWITCHING FOR OPTICAL PICKUPS DETECTOR PATTERN ADAPTED FOR EFM SIGNAL DETECTION, FOCUS AND TRACKING CONTROLS OPTOSO10L (Plastic Transparent Package) DESCRIPTION This six diodes photodetector includes six low noise I/V amplifiers with a sensitivity switching for adaptation to different optical pickups and disks. The detector pattern is adaptable for astigmatism focus method, 3 beams tracking and differential phase detection methods. The STV5805 is adapted for pick-up of DVD-ROM and DVD players up to 3 x speed for both 1 layer and 2 layer discs.
