General Description
The EL6291C is a highly integrated laser diode driver designed to sup-
port 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 cir-
cuitry 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 EL6291C requires 3.3V and 5V supplies, with all the logical
interface operating on the 3.3V supply.
The EL6291C is available in 32-pin LPP and 32-pin QFN packages
for improved thermal performance and reduced footprint.
