3-Channel Laser Diode Driver w/Oscillator

& APC Amplifier

grounded laser diode. 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

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

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 output

current modulation when in any mode. This is turned on only

when the OSCEN and OUTEN pins are held high. Complete

control of amplitude and frequency is set by two external

resistors connected to ground at pins R

(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

ENABLE pin low, which will override all other control pins.

The EL6245 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.

Ordering Information

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.
