LMH6533 Four - Channel Laser Diode Driver with Dual Output, LVDS Interface and HFM Oscillator May 2004 LMH6533 Four - Channel Laser Diode Driver with Dual Output, LVDS Interface and HFM Oscillator General Description The LMH™ 6533 is a laser diode driver for use in bination DVD/CD recordable and rewritable systems. The part contains two high-current outputs for reading and writing the DVD (650 nm) and CD (780 nm) lasers. Functionality includes read, write and erase through four separate switched current channels. The channel currents are summed together at the selected output to generate multilevel waveforms for reading, writing and erasing of optical discs. The LVDS interface delivers...
