CXA2598M - PDIC for CD-R/RW

General 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).

Key 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).

CXA2598M PDIC for CD-R/RW 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 Structure Bipolar silicon monolithic IC Absolute Maximum Ratings (Ta = 25°C) • Supply voltage VCC 5.
