DESCRIPTION
The SP8050A 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.
The SP8050A is manufactured with an advanced, fully complementary proprietary BiCMOS
process that enables integration of on-board multiple photo detector arrays
