GENERAL DESCRIPTION
The SP8059 is a ten-channel photo detector IC (PDIC) designed for new generation of Blu-Ray
DVD and standard DVD/CD applications and can operate at wavelengths of 405, 650 and 780
nm. The device contains three photo diode (sensor) arrays, one of them with four identical
sensors A 鈥?D and the other two with two sensors each (E, F and G, H respectively). The ten
channels consist of four high speed channels (A, B, C, and D), four slow channels (E, F, G, and
H), and two RF channel with paraphrase output (RF+ and RF-). The high speed channels output
a signal from one of the sensors A 鈥?D. The E, F, G, and H channel outputs are used for servo
control. The RF channels output is the sum of A + B + C + D channels with identical weights
given to all channels.
Three Gain select inputs allow the setting of eight gain modes and a Power Down mode with low
power consumption if Gain 0 input is left floating.
Low noise operation enables data recovery at very low signal levels.
