FEATURES
APPLICATIONS
■ DVD Player
The SP8042 is a seven channel photo detector IC (PDIC) designed for DVD-ROM and CD-ROM
applications and can operate at wavelength of 650 and 780 nm. The device contains four photo
diode (sensor) arrays, two of them with four identical sensors (A – D, and a - d respectively) and
two with a single sensors (E, F). The seven channels consist of four high speed channels (Aa,
Bb, Cc, and Dd), two slow channels (E, F), and one RF channel. The high speed channel output
provides a signal from one of the two different sensor arrays (A – D or a – d) depending the position
of the media switch (SW). A high logic level at the SW pin selects CD mode (A – D sensors) while
a low level selects DVD mode (a – d sensors). The E and F channels output is used for a servo
control. The RF channels output is sum of A + B + C + D or a + b + c + d channels (depending
upon SW level) with identical weights given to all channels.
Low noise operation enables data recovery at very low signal levels.
The SP8042 is manufactured with an advanced 10GHz BICMOS technology.
