| (R) Preliminary SP8051 8 Channel, 140MHz Fully Integrated PDIC Receiver with Gain Switching Data channel bandwidth140MHz Settling Time: 9ns to 1% for 1.5V step Three selectable Gain Settings Group DelayError less than 2ns up to 70MHz Low Offset Drift of less than 20uV/ C Low Offset Voltage of less than 10mV VREF SW1 SW2 H+L G+K F+J E+I GND 1 2 3 4 5 6 7 8 16 VCC 15 D SP8051 16 Pin COB 14 C 13 RF+ 12 RF11 B 10 A 9 GND DESCRIPTION The SP8051 is a high performance 8 channel PDIC with a fully integrated photo detector array ideally suited for high speed DVDRW, DVDRAM and CDRW systems. 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 SP8051 is manufactured with an advanced, fully complementary proprietary BiCMOS process that enables integration of on-board multiple photo detector arrays.
