Laser Diode Driver with Waveform

Generator

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 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 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 clock and NRZ

inputs can be either standard CMOS or LVDS, selectable

through a program bit.

The EL6196 operates on a 5V supply for the analog circuits

and a 3.3V supply for the digital circuits.

Ordering Information

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.
