EL6291C - Product Brief

Laser Diode Driver with Waveform Generator

Features

General Description

• Complete programmable laser

diode driver

• 250mA maximum output

• 8bit x 8bit multiplying DAC output

provides 8bit full scale adjustment

and 8bit resolution at any full scale

output

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.

• 0.17 nsec timer resolution

• Two laser outputs allows

read/write DVD and CD

combinations

• Programmable waveform values

support 2.6GB DVD-RAM, 4.7GB

DVD-RAM, DVD-R, DVD+RW,

DVD-RW, CD-RW, and CD-R

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.

• Analog input supports APC

• HFM oscillator programmable to

100mA_P-Pfrom 200MHz to

600MHz

The EL6291C is available in 32-pin LPP and 32-pin QFN packages

for improved thermal performance and reduced footprint.

• PLL allows reduced-frequency

clock on flex cable

• Separate serial input works up to

25Mb/sec
