GENERAL DESCRIPTION

The SP8056 is a ten channel photo detector IC (PDIC) specially designed for high speed DVDRAM and DVD-RW applications and can operate at wavelength of 650 and 780 nm. The ten channels consist of four high speed channels (A, B, C, and D), two average speed channels (EF and GH), two slow channels (SAD and SBC), and two channels with paraphase output (RF+ and RF-). The EF and GH channels output is sum of signals from E + F and G + H sensors respectively. The RF channels output is sum of A + B + C + D + EF + GH channels with identical weights. Low noise operation enables data recovery at very low signal levels.
