Laser Diode Driver with Waveform
Generator
The EL6900 is a highly integrated
laser diode driver designed to support
Blu-Ray 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 2, 3, 4, or 5 or
more clock periods of space changing to 2, 3, 4, or 5 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 all output
waveform parameters. 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 EL6900 operates on a 5V supply for the analog circuits
and a 3.3V supply for the digital circuits.
