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. 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.

BOARD LAYOUT AND GROUNDING To obtain the best performance from the SP8059, a printed circuit board with ground plane is required. Ground pins (pin #6) should be connected to the ground plane. High quality, low series resistance ceramic 0.1uF bypass capacitors should be used at the Vcc and Vref pins (pins #3 and #14). These capacitors must be located as close to the pins as possible. The traces connecting the pins to the ground plane, Vcc, Vref, and bypassing capacitors must be kept short and should be made as wide as possible.
