Description  
The ATR0841 is a laser diode driver designed to operate two differently grounded  
laser diodes for DVD-RW/+RW (650 nm) and CD-RW (780 nm). The device includes  
four channels for four different optical power levels. The write channels (channel 2 to  
4) can be controlled by fast LVDS (Low Voltage Differential Signaling). Due to the inte-  
grated termination external resistors are not needed.  
ATR0841  
Summary  
The function of the read channel is to generate a continuous output current, channels  
2 to 4 are designed as write channels with very fast switching speed. All channels are  
summed together and routed to one of the two outputs, IOUTA or IOUTB, controlled  
by the select input SELA. Each write channel (channels 2 to 4) can contribute up to  
350 mA to the total output current of up to 500 mA. The read channel can contribute  
up to 150 mA. Total gain of 100 (read channel) and 250 (channel 2, 3 and 4), respec-  
tively, are provided between each reference current input and the selected output.  
Although the reference inputs are current inputs, voltage control is possible by using  
external resistors. An on-chip RF oscillator is available to reduce laser-mode hopping  
noise during read mode. The oscillator current amplitude can be set independently for  
the two selectable outputs with two different resistors. Oscillation is enabled by a high  
signal at the ENOSC pin. Complete shut down of the output currents is achieved by a  
low signal at the ENABLE input.  
In case of uncertain (balanced) enable signals, a built-in protection circuit keeps the  
laser diode output current within the defined range.
