High Speed 12-channel Photo Detector Ic Corporation

The SP8052 is a twelve-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 twelve channels consist of four high speed channels (A, B, C, and D), four slow channels (EI, FJ, GK, and HL), two fast channels (WPP1 and WPP2), and two channels with paraphase output (RF+ and RF-). The slow channels output is the sum of signals from two Sensors of different Sensor arrays (E H and I L). The WPP1 and WPP2 channels output is sum of signals A + B and C + D Sensors respectively, but at much lower gain (than at A D outputs) to prevent Amplifier saturation in write mode. The RF channels output is sum of A + B + C + D channels with identical weights. Low noise operation enables data recovery at very low signal levels. The SP8052 has a Logic input for gain control that operate as a three-state Logic input (Low, Mid, and High states). These states are used to select three gain factors that affect all channels. The SP8052 is manufactured with an advanced 10GHz BICMOS technology. By Exar Corporation
