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.

BOARD LAYOUT AND GROUNDING
To obtain the best performance from the SP8064, 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. A Vref
decoupling capacitor to ground should be used. 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.
