CXA2586

CXA2586M PDIC for CD-ROM/DVD-ROM Description CXA2586M is a PDIC (photodetector IC) developed as a photodetector for the optical pickup of CD-ROM/DVD-ROM. The photodiode and circuit blocks operate at high speed. (Typ. 100MHz) Focus servo : astigmatic method Tracking servo (CD) : three-spot method Tracking servo (DVD) : differential phase detection method Features High-speed I-V amplifier (current-voltage conversion circuit) High-speed photodiode Adding amplifier (addition of A to D) Compact transparent molded package (SOP) Applications Optical pickup for CD-ROM/DVD-ROM PD-S-19-B (Plastic) Absolute Maximum Ratings (Ta=25 °C) Supply voltage VCC 5.5 V Operating temperature Topr –10 to +70 °C Storage temperature Tstg –40 to +100 °C Allowable power dissipation 300 mW PD Operating Conditions Supply voltage1 Supply voltage2 VCC VC 4.5 to 5.5 1.5 to VCC–1.5 V V Structure Bipolar silicon monolithic IC Block Diagram and Pin Configuration Fo 10 VCC VC GND Eo 9 8 7 6 Ao Bo Co Do VREF 1 Do 2 Ao 3 RF 4 Bo 5 Co ∗ The components marked by A, B, C, D, E and F are the photodiodes (photo sensitivity.
