PDIC for CD-ROM/DVD-ROM
CXA2586M
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)
PD-S-19-B (Plastic)
• Focus servo : astigmatic method
• Tracking servo (CD)
: three-spot method
• Tracking servo (DVD)
: differential phase detection method
Features
