Laser Diode Driver with Waveform  
Generator  
Features  
• Complete programmable laser diode driver  
• 600mA maximum total output  
The EL6939 is a highly integrated laser diode driver  
designed to support multi-standard writable optical drives. It  
accomplishes this by incorporating a waveform generator  
wherein the diode currents and timing details can be  
programmed before operation. The data input circuitry  
inspects the NRZ serial data waveform and generates  
programmed waveforms in recognition of 3, 4, 5, or 6 or  
more clock periods of space changing to 3, 4, 5, or 6 or more  
clock periods of mark, and vice versa.  
• 10-bit x 10-bit multiplying DAC output provides 10-bit full  
scale adjustment and 10-bit resolution at any full scale  
output  
• 54 psec timer resolution  
• Two laser outputs allows read/write DVD and CD  
combinations  
• Programmable waveform values support CD-R, CD-RW,  
DVD-RAM, DVD-R, DVD-RW, DVD+R, DVD+RW, and  
Blue  
The architecture allows reprogramming of the timers to  
support different media, Blue, DVD, or CD standards, and  
different speeds. The programming is accomplished through  
a serial interface port. Two outputs are provided to support  
dual-laser multi-standard optical heads. The clock and NRZ  
inputs can be either standard CMOS or LVDS, selectable  
through a program bit.  
• Two analog inputs support slope and read APC  
• HFM oscillator programmable to 100mA  
to 500MHz  
from 100MHz  
P-P  
• PLL allows reduced-frequency clock on flex cable  
• Separate serial input works up to 100MHz  
• Programmable HFM offset when HFM is off  
• Pb-free available (RoHS compliant)  
The EL6939 requires 2.5V and 5V supplies, with all the  
logical interface operating on the 2.5V supply.

NOTE: Intersil Pb-free products employ special Pb-free material sets;  
molding compounds/die attach materials and 100% matte tin plate  
termination finish, which are RoHS compliant and compatible with  
both SnPb and Pb-free soldering operations. Intersil Pb-free products  
are MSL classified at Pb-free peak reflow temperatures that meet or  
exceed the Pb-free requirements of IPC/JEDEC J STD-020C.  
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
