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, 9 10 11 12 13 14 15 16 VREF SW1 SW2 H+L G+K F+J E+I GND A B RFRF+ C D VCC Reference Voltage Gain Select 1 Gain Select 2 Tracking Channel Sum Tracking Channel Sum Tracking Channel Sum Tracking Channel Sum Power Ground Data Channel Data Channel RF Sum Minus (A to D) RF Sum Plus (A to D) Data Channel Data Channel Supply Voltage Rev. 4/30/03 SP8050A, 8 Channel, 150MHz PDIC Receiver with Gain Switching © Copyright 2003 Sipex Corporation 2 PACKAGE: 16 PIN COB PDIC (8ch + RF + GAIN - SW) (12-divided detector) Package Size (Unit: mm) 1 16 Package Size (Unit: µm) 150 ± 0.1 L P0.5 x 7 = 3.5 72.5 150 21 72.5 5 K 5 4 4.9 ± 0.1 3.9 ± 0.1 3.7 ± 0.1 16 - 0.25 I 64.75 21 J Detected Surface 0.35 150 C D 5 A B 64.75 G PIN NUMBER 1 2 3 4 5 6 7 8, 9 10 11 12 13 14 15 16 NAME VREF SW1 SW2 H+L G+K F+J E+I GND A B RFRF+ C D VCC H 150 E 5 F Rev. 4/30/03 SP8050A, 8 Channel, 150MHz PDIC Receiver with Gain Switching © Copyright 2003 Sipex Corporation 3 ORDERING INFORMATION PART NUMBER TEMPERATURE RANGE PACKAGE SP8050A .............................................................................. -30°C to +80°C ................................................................................. 16 lead COB Corporation SIGNAL PROCESSING EXCELLENCE Sipex Corporation Headquarters and Sales Office 22 Linnell Circle Billerica, MA 01821 TEL: (978) 667-8700 FAX: (978) 670-9001 e-mail: sales@sipex.com Sales Office 233 South Hillview Drive Milpitas, CA 95035 TEL: (408) 934-7500 FAX: (408) 935-7600 Sipex Corporation reserves the right to make changes to any products described herein.
