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.
