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 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). In sleep mode
all channels are in tri-state condition.
The SP8058 is manufactured with an advanced 10GHz BICMOS technology.
