High Speed 11-channel Photo Detector IC

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. By Exar Corporation
