... Recordable Optical Drives Description The ATR0840 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 can be controlled either by fast LVDS (Low Voltage Differential Signaling sin- gle-ended standard CMOS logic ...
