EL6215
3-Channel Laser Diode Driver + Oscillator
The EL6215 is a high-performance
three channel laser driver that
provides controlled current to a
grounded laser diode. Write channels 2 and 3 should be
used as the write channels, 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 RFREQ and RAMP (see graphs
in this data sheet for further explanation).

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.
