Laser Driver
CXA2610AN
Preliminary
Description
The CXA2610AN is a laser driver IC for optical
discs. This IC supports higher optical power output
speeds.
16 pin SSOP (Plastic)
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.
