EL6296
Laser Diode Driver with Waveform
Generator
The EL6296 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.
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 EL6296 requires 3.3V and 5V supplies, with all the
logical interface operating on the 3.3V 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 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.
