The EL6298 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. NRZ and clock are
LVDS.
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 EL6298 requires 3.3V and 5V supplies, with all the
logical interface operating on the 3.3V supply.
The EL6298 is available in 32-pin QFN and 32-pin QFN
packages for improved thermal performance and reduced
footprint.
