Laser Diode Driver with Waveform

Generator

Features

• Complete programmable laser diode driver

The EL6938 is a highly integrated

laser diode driver designed to support

• 500mA maximum total output

• 10-bit x 10-bit multiplying DAC output provides 10-bit full

scale adjustment and 10-bit resolution at any full scale

output

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.

• 54 psec timer resolution

• Two laser outputs allows read/write DVD and CD

combinations

• Programmable waveform values support CD-R, CD-RW,

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

Blue

The architecture allows reprogramming of the timers to

support different media, Blue, 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 clock and NRZ

inputs can be either standard CMOS or LVDS, selectable

through a program bit.

• Two analog inputs support slope and read APC

• HFM oscillator programmable to 100mA

to 500MHz

from 100MHz

P-P

• PLL allows reduced-frequency clock on flex cable

• Separate serial input works up to 100MHz

• Programmable HFM offset when HFM is off

• Pb-free available

The EL6938 requires 2.5V and 5V supplies, with all the

logical interface operating on the 2.5V supply.

Applications

• Combination DVD writable and CD writable drives

• DVD camcorders

• DVD video recorders

NOTE: Intersil Pb-free products employ special Pb-free material

sets; molding compounds/die attach materials and 100% matte tin

plate termination finish, which is compatible with both SnPb and

Pb-free soldering operations. Intersil Pb-free products are MSL

classified at Pb-free peak reflow temperatures that meet or exceed

the Pb-free requirements of IPC/JEDEC J Std-020B.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
