ATR0839 Datasheet 4-channel Lvds Laser Driver

Manufacturer: Atmel (now Microchip Technology)

Overview: ..

General Description

The ATR0839 is a laser diode driver designed to operate two different grounded laser diodes for DVD-RW/DVD+RW (650 nm) and CD-RW (780 nm).

The device includes four channels for four different optical power levels.

The write channels (channels 2 to 4) can be controlled by fast LVDS (Low Voltage Differential Signaling).

Key Features

  • Current-controlled Output Current Source with 4 Input Channels LVDS Compatible Inputs at Channels 2, 3 and 4 with On-chip 100Ω Termination Separate Read-channel Enable Two Selectable Outputs for Grounded Laser Diodes Output Current per Channel up to 350 mA Total Output Current up to 600 mA On-chip RF Oscillator with LVDS Enable Control of 2 Different Swings and Frequencies by u.
