GENERAL DESCRIPTION
SP8064 ten-channel photo detector (PDIC) designed applications operating wavelengths device contains three photo diode (sensor) arrays, them with four identical sensors other with sensors respectively). channels consist four high speed channels four slow channels channel with balanced differential outputs (RF+ RF-). Channels through high bandwidth data channels, while through used generate tracking information. channels output channels with identical weights given channels. Three Gain select inputs (R/W, H/L, C/D) allow setting eight gain modes Power Down mode with power consumption inputs left floating driven Hi-Z logic levels respectively. SP8064 manufactured with advanced 10GHz BICMOS technology.

BOARD LAYOUT GROUNDING
obtain best performance from SP8064, printed circuit board with ground plane required. Ground pins (pin should connected ground plane. High quality, series resistance ceramic 0.1uF bypass capacitors should used Vref pins (pins #14). These capacitors must located close pins possible. Vref decoupling capacitor ground should used. traces connecting pins ground plane, Vcc, Vref, bypassing capacitors must kept short should made wide possible.
