GENERAL DESCRIPTION

The SP8057 is an eleven-channel photo detector IC (PDIC) specially designed for high speed

DVD-RAM and DVD+/-RW applications and can operate at wavelengths of 650 and 780 nm.

The device contains three photo diode (sensor) arrays, with each having four sensors (A – D, E

– H, and I – L respectively). The eleven channels consist of four high speed channels (A, B, C,

and D), four slow channels (EI, FJ, GK, and HL), two fast channels with paraphase output (RF+

and RF-), and one additional WRF channel. The four slow channels output is the sum of signals

from two sensors of the same sensor array (E + I, F + J, G + K, and H + L). The WRF channels

output is four times the sum of A + B + C + D channels, while the output signal of paraphase

channels RF+ and RF- is only 0.5 of this sum. Low noise operation enables data recovery at

very low signal levels.

The SP8057 has two logic inputs for gain control that operate as three-state logic input (Low,

Mid, and High states). These states are used to select gain factors that affect all channels.

The SP8057 is manufactured with an advanced 10GHz BICMOS technology.
