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.
