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. Three Gain select inputs (R/W, H/L, C/D) allow setting of eight gain modes and a Power Down mode with low power consumption if H/L and C/D inputs are left floating or driven to Hi-Z and low logic levels respectively. The SP8064 is manufactured with an advanced 10GHz BICMOS technology.
