Responsivity is fully specified at wavelengths of 650nm and 780nm. The 8 channels consist of 4 high speed channels (A, B, C, D) for data detection as well as 4 tracking channels (E, F, G, H) for beam positioning requirements. Two additional outputs (RF+ and RF-) representing the sums of the high speed channels are also provided. The SP8050A is manufactured with an advanced, fully complementary proprietary BiCMOS process that enables integration of on-board multiple photo detector arrays VCC A VA B VB C VC D VD E I F J G K GND H L V (E + I) V (F + J) V (G + K) V (H + L) VS BIAS CIRCUIT-1 VRF + (A-D) SW1 (GAIN) VA VB VC VD BIAS CIRCUIT - 1 SW2 (GAIN) BIAS CIRCUIT - 2 VRF - (A-D) SP8050A Functional Diagram Rev. 4/30/03 SP8050A, 8 Channel, 150MHz PDIC Receiver with Gain Switching © Copyright 2003 Sipex Corporation 1 PIN DESCRIPTION PIN NUMBER NAME DESCRIPTION 1 2 3 4 5 6 7 8,...
