描述 Description

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

特性 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
