EL6938
Laser Diode Driver with Waveform
Generator
The EL6938 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.
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.
The EL6938 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 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.
