EL6290C - Product Brief

Laser Diode Driver with Waveform Generator

General Description

The EL6290C 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 EL6290C operates on a 5V supply, but has a separate logical

interface supply for 3.3V interface operation.

The EL6290C is availiable in a 24-lead QSOP, or in a 32-lead QFN

package for improved thermal performance and reduced board area

usage.
