EL6935B
Laser Diode Driver w/ Waveform Generator
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.
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.
The EL6935B operates on a 5V supply for the analog circuits
and a 2.5V supply for the digital circuits.

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.
