PDIC for CD-R/RW
CXA2598M
Description
The CXA2598M is a PDIC (photodetector IC)
developed as a photodetector for the optical pickup
of CD-R/RW. The photodiode and I-V amplifier operate
at high speed (100MHz). When the strong light is
emitted during write, the delay or ringing is not
occurred because the limiter circuit is included in the
I-V amplifier.
• Focus servo: astigmatic method
• Tracking servo: differential push-pull method
Features
• I-V amplifier (current-voltage conversion circuit)
• RF output of addition of A to D signals
• Wide band (100MHz typ.)
• Output limiter circuit
• Small transparent molded package (SOP)
