EL6291C - Product Brief  
Laser Diode Driver with Waveform Generator  
Features  
General Description  
• Complete programmable laser  
diode driver  
• 250mA maximum output  
• 8bit x 8bit multiplying DAC output  
provides 8bit full scale adjustment  
and 8bit resolution at any full scale  
output  
The EL6291C is a highly integrated laser diode driver designed to sup-  
port 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 cir-  
cuitry 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.  
• 0.17 nsec timer resolution  
• Two laser outputs allows  
read/write DVD and CD  
combinations  
• Programmable waveform values  
support 2.6GB DVD-RAM, 4.7GB  
DVD-RAM, DVD-R, DVD+RW,  
DVD-RW, CD-RW, and CD-R  
This programmable architecture allows reprogramming of the timers  
to support different media, 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 EL6291C requires 3.3V and 5V supplies, with all the logical  
interface operating on the 3.3V supply.  
• Analog input supports APC  
• HFM oscillator programmable to  
100mAP-P from 200MHz to  
600MHz  
The EL6291C is available in 32-pin LPP and 32-pin QFN packages  
for improved thermal performance and reduced footprint.  
• PLL allows reduced-frequency  
clock on flex cable  
• Separate serial input works up to  
25Mb/sec
