Laser Diode Driver w/ Waveform Generator

Features

The EL6935 is a highly integrated

laser diode driver designed to support

multi-standard writable optical drives.

• Complete programmable laser diode driver

• 450mA 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

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. The part also has an

IV amplifier with concurrent read and write sampling. The

gains of the IV amplifier are programmable, eliminating the

need for external potentiometers.

• 60psec 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

• Two analog inputs support slope and read APC

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.

• 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

• Dual sampled IV amplifier with programmable sample

select and gain select

The EL6935 operates on a 5V supply for the analog circuits

and a 2.5V supply for the digital circuits.

• Programmable HFM offset when HFM is off
