This is advance information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
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.
