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.

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.
