EL6173
3-Channel Laser Diode Driver w/Oscillator
& APC Amplifier
The EL6173 is a high performance
three-channel laser driver that
provides controlled current to a
grounded laser diode. Write channels 2 and 3 can provide
up to 200mA per channel of DC or pulsed current, with
switching speeds of approximately one nanosecond rise/fall
time. All three channels are summed together at the I
OUT
output, allowing the user to create multilevel waveforms in
order to optimize laser diode performance. The level of the
output current is set by an analog voltage applied to an
external resistor which converts the voltage into a current at
the I
IN
pin (virtually ground). The current seen at this pin is
then amplified to become a current source at pin I
OUT
.
An on-chip 500MHz oscillator is provided to allow output
current modulation when in any mode. This is turned on
when the OSCEN pin is held high. Complete control of
amplitude and frequency is set by two external resistors
connected to ground at pins R
FREQ
and R
AMP
(see graphs
in this data sheet for further explanation.)
Output current pulses are enabled when an ‘L signal is
applied to the OUTEN pin. No output current flows when
OUTEN is ‘H’ and additional laser diode protection is
provided since the OUTEN input will float high when open.
Complete I
OUT
shut-off is also achieved by holding the
ENABLE pin low, which will override all other control pins.
The EL6173 also includes a fast-settling APC amplifier
designed to interface directly with the front end monitor
diode and the sample-and-hold amplifier for read and write
power control. Its 100MHz bandwidth and 30ns settling time
enable up to 16X CD-RW design.

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.
