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

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

(virtually ground). The current seen at this pin is then

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.
