The SP8051 is a high performance 8 channel PDIC with a fully integrated photo detector array ideally suited for high speed DVDRW, DVDRAM and CDRW systems. Responsivity is fully specified at wavelengths of 650nm and 780nm. The 8 channels consist of 4 high speed channels (A, B, C, D) for data detection as well as 4 tracking channels (E, F, G, H) for beam positioning requirements. Two additional outputs (RF+ and RF-) representing the sums of the high speed channels are also provided.
