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)

Note 1) Output offset voltage: Vc is the reference.
Note 2) Output voltage: Vc is the reference. However, the offset voltage is excluded.
Note 3) Output voltage, offset temperature drift, frequency response, group delay difference, settling time,
slew rate: Confirmation of design.
Note 4) Measurement by the optical input: Measurement is made by emitting the light to the center of each
photodiode.
