EL6287C - Product Brief

4-Ch Laser Diode Driver + Oscillator

General Description

The EL6287C is a four channel laser diode current amplifier that pro-

vides controlled current to a grounded laser diode. Channels 2, 3, and

4 must be used as the write channels, with switching speeds of approx-

imately one nanosecond rise/fall time. All four channels are summed

together at the I

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

ally ground). The current seen at this pin is then amplified to become a

current source at pin I

An on-chip 500MHz oscillator is provided to allow current modula-

tion when in read mode. This is turned on when the OSCEN pin is held

high. Complete control of amplitude and frequency is set by two exter-

nal resistors connected to ground at pins RFREQ and RAMP (see

graphs in this data sheet for further explanation). The oscillator will

turn off whenever any of the OUTEN pins for channels 2, 3, or 4 (the

write channels) are low (see truth table).

The external resistors allow the user to accurately and independently

set each amplifier transconductance by applying a voltage to each

resistor, without restriction on the voltage range, thus ensuring broad

voltage DAC compatibility. Alternatively, the I

from a current DAC or other current source.
