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
