Laser Diode Driver with Waveform
Generator
Features
• Complete programmable laser diode driver
• 350mA maximum total output
The EL6900 is a highly integrated
laser diode driver designed to support
• 8-bit x 8-bit multiplying DAC output provides 8-bit full scale
adjustment and 8-bit resolution at any full scale output
Blu-Ray 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 2, 3, 4, or 5 or
more clock periods of space changing to 2, 3, 4, or 5 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.
• 120ps timer resolution
• Blu-Ray Disc standard
• 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 25MHz
The architecture allows reprogramming of all output
waveform parameters. The programming is accomplished
through a serial interface port. The clock and NRZ inputs can
be either standard CMOS or LVDS, selectable through a
program bit.
• Dual sampled IV amplifier with programmable sample
select and gain select
• Programmable HFM offset when HFM is off
Applications
The EL6900 operates on a 5V supply for the analog circuits
and a 3.3V supply for the digital circuits.
• Blu-Ray ultra-density optical (UDO) drives
• Blu-Ray consumer HDTV video recorders
