DESCRIPTION

Gain of 300, 300 mA Write Channel  
The LMH™6525/6526 is a laser diode driver for use  
in combination 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 DVD write speeds  
of 16x and higher while minimizing noise and  
crosstalk. The LMH6525/6526 is optimized for both  
speed and power consumption to meet the demands  
of next generation systems. The part features a 150  
mA read channel plus one 300 mA and two 150 mA  
write channels, which can be summed to allow a total  
output current of 600 mA or greater. The channel  
currents are set through four independent current  
inputs.
