OPIC Light Detector
OPIC Light Detector for X40 Speed CD-ROM Drive
Sharp's
IS1682
is OPIC light detectors which
are used for pick-up in X40 speed CD-ROM drive.
They improve noise resistance characteristics and
enable to read low reflective CD-RW due to built-in
RF amp.
(1) High speed response(Response frequency: MIN. 45MHz)
(Best suited for optical pick-up in X40 speed CD-ROM drive)
(2) With built-in RF amplifier
(Integrates 6-division PIN photodiode and
amplifier circuit onto a single chip)
(3) Compact and thin package
(Dimensions: 5.0 x 4.0 x 1.5mm)
(4) Possible to supply custom-made detecting pattern
(5) Pair use with Sharp's laser diode is recommended.
Laser diode : 780 nm / 5 mW (LT022 series )
770 to 795 nm /60 mW ( LT041NS )
(1) CD-ROM drive(to 40X speed)
(2) CD-ROM drive for CD-RW
* "OPIC"(Optical IC)is a trademark of the SHARP Corporation. An OPIC consists of a
light-detecting element and signal-processing circuit integrated ontoa single chip.
