Description
The CXA2610N 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
