Laser Diode Driver w/ 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, 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 EL6935 operates on a 5V supply for the analog circuits

and a 2.5V supply for the digital circuits.
