GENERAL DESCRIPTION
The SP8067 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 summing channels with differential
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 differential channels RF+ and RF- is only 0.5 of this sum.
The SP8067 has two logic inputs for gain control that operate as tri-state logic input (Low, Mid,
and High states). These states are used to select gain factors that affect all channels. The
WRF channel is active only during Write Modes, while the RF+ and RF- channels are active
only during Read Modes. If not active, the WRF channel is in tri-state (Hi-Z) mode, while the RF
channels are fixed at their respective reference voltages (2.0v for RF+ and 3.0v for RF-
channel).
The SP8067 is manufactured with an advanced 10GHz BICMOS technology.
