PHOTO DETECTOR FOR DIGITAL VIDEO DISK
.
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
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 adapt able for astigmatism
focus method, 3 beams tracking and differential
phase detection methods.
The STV5805 is adapted for pick-up of DV D-ROM
and DVD players up to 3 x speed for both 1 layer
and 2 layer discs.
