SP8059W中文资料西伯斯数据手册PDF规格书

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 – 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 – 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.
