GENERAL DESCRIPTION
The SP8058 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), two average speed channels (EF
and GH), two slow channels (SAD and SBC), and two channels with balanced differential output
(RF+ and RF-). The EF and GH channels output is sum of signals from E + F and G + H
sensors respectively. The RF channels output is sum of A + B + C + D + EF + GH channels with
identical weights.
The SP8058 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
14 logic states are used to select 11 gain factors, an adjustment mode, and a sleep mode (see
table 4). Adjustment mode is used to adjust the position of the PDIC with respect to the laser
beam. In this mode each of the sensors E, F, G, and H is connected to the input of EF, GH,
SAD, and SBC channels respectively instead of the standard configuration. In sleep mode all
channels are in tri-state condition.
The SP8058 is manufactured with an advanced 10GHz BICMOS technology.
