Laser Diode Driver w/ Waveform Generator
Features
• Completely programmable laser diode driver
The EL6935B 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 generator 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. The part also has an IV
amplifier with concurrent read and write sampling. The gains
of the IV amplifier are programmable, eliminating the need
for external potentiometers.
• 500mA maximum total output
• 10-bit x 10-bit multiplying DAC output provides 10-bit full
scale adjustment and 10-bit resolution at any full scale
output
• 55psec 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 flexible architecture supports different media and
speeds for Blue, DVD, and CD standards. The programming
is accomplished through a serial interface port. 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
The EL6935B operates on a 5V supply for the analog circuits
and a 2.5V supply for the digital circuits.
• Dual sampled IV amplifier with programmable sample and
gain selects
Ordering Information
• Programmable DC output when HFM is off
• Pb-free available

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is 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-020B.
