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.

... CC BOARD LAYOUT AND GROUNDING To obtain the best performance from the SP8057, a printed circuit board with ground plane is required. High quality, low series resistance ceramic 0.1uF bypass capacitors should be used at the Vcc and Vs pins (pins 1 and 16). These capacitors must be located as close to the pins as possible ...
