GENERAL DESCRIPTION

The SP8064 is a ten-channel photo detector IC (PDIC) designed for DVD and CD applications operating at wavelengths of 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 (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 balanced differential outputs (RF+ and RF-). Channels A through D are high bandwidth data channels, while E through H are used to generate tracking information. The RF channels output the sum of A + B + C + D channels with identical weights given to all channels.
