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)

Applications

Optical pickup for CD-R/RW
