Description

The CXA2610AN is a laser driver IC for optical discs. This IC supports higher optical power output speeds.

Features

• LD driver with excellent driving capability

• Write current of 250mA (max.) possible by setting the IIN2 (Pin 2) and IIN3 (Pin 5) external resistors

• Rise time ≈ 3ns

• Fall time ≈ 4ns

• The oscillation frequency of the built-in oscillation circuit can be set from 100 to 600MHz by connecting the OSCFR (Pin 4) external resistor to GND.

• The oscillator amplitude initial value of the built-in oscillation circuit can be set by connecting the OSCGA (Pin 12) external resistor to GND, and the oscillator amplitude can be adjusted by the IINR input current value.

• Oscillation ON/OFF can be set as desired.

• Single +5V power supply

• TTL/CMOS control for control system

Applications

• CD-R driver

• CD-RW driver

• DVD driver

• Writable optical driver

• Laser diode current switching
