SP8042DB

The SP8042DB is one member of the SP8042 series.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.

Features of the SP8042DB are:(1)dual wave length 650 and 780nm; (2)55MHz data channel bandwith; (3)built-in media switch; (4)available in wafer form or 5.0 x 4.0mm 16 pin COB package.The high speed channel output provides a signal from one of the two different sensor arrays (AD or ad) depending the position of the media switch (SW). A high logic level at the SW pin selects CD mode (AD sensors) while a low level selects DVD mode (ad 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.

The absolute maximum ratings of the SP8042DB can be summarized as:storage temperature:-30 to 80.The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics.
