GENERAL DESCRIPTION
The SP8062 is a ten channel photo detector IC (PDIC) specially designed for high speed DVD-
RAM and DVD-RW applications and can operate at wavelength of 650 and 780 nm. The ten
channels consist of four high speed channels (A, B, C, and D), four average speed channels (E,
F, G, and H), and two channels with paraphase output (RF+ and RF-). The RF channels output
is sum of A + B + C + D channels with identical weights. Low noise operation enables data
recovery at very low signal levels.
The SP8062 has three logic inputs for gain control, one of them operating as TTL compatible
(Gain 1), and two other operating as three state logic inputs (Gain 2 and Gain 3). The allowable
logic states are used to select 10 gain factors and a sleep mode (see table 4).
In sleep mode all channels are in tri-state condition.
The SP8062 is manufactured with an advanced 10GHz BICMOS technology.
