ATR0842 Datasheet 4-channel Lvds Laser Diode Driver

Manufacturer: Atmel (now Microchip Technology)

General Description

The ATR0842 is a laser diode driver designed to operate two differently grounded laser diodes.

The output, IOUTA, can be used for a blue laser diode (400 nm) with up to 6 V voltage drop by applying 8 V at pin VCCH.

The other output, IOUTB, supports legacy laser diodes for DVD-RW/+RW/RAM (650 nm) and CD-RW (780 nm).

Key Features

  • Current-controlled Output Current Source with 4 Input Channels Two Selectable Outputs for Grounded Laser Diodes Output A Suited for Blue Laser Diodes: VLD ≤6 V (VCCH ≤8 V) LVDS/CMOS Compatible Inputs Channel 2, 3, and 4 Output Current per Channel up to 350 mA Total Output Current up to 500 mA On-chip RF Oscillator Control of 2 Different Frequencies and Swings by Use of 4 External Resistors.
  • Oscillator Freque.
