DESCRIPTION
The SP8040 is a high performance 4 channel PDIC with a fully integrated photo detector array
ideally suited for high speed DVDRW, DVDRAM and CDRW systems that incorporate separate
paths for CD and DVD information. Responsivity is fully specified at 650nm. There are 4 high
speed channels (A, B, C, D) for data detection and an additional output, V
RF
, representing the
sum of the high speed channels.
The SP8040 is manufactured with an advanced, CMOS process that enables integration of on-
board multiple photo detector arrays.
