EL6288C - Product Brief

3-Channel Laser Diode Driver w/Oscillator & APC Amplifier

Features

General Description

• Shrink-Small Package Outline

The EL6288C is a high-performance three channel laser driver that

provides controlled current to a 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_OUToutput, allowing the user to create multi-

level 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_INpin

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

• Voltage-controlled output current

source, requiring one external set

resistor per channel

• Current-controlled output current

source

• Rise time = 0.8ns

• Fall time = 0.8ns

• On chip oscillator with frequency

and amplitude control by use of

external resistors to ground

• Oscillator to 500MHz

• Oscillator to 100mA pk/pk

• Single +5V supply (±10%)

• Disable feature for power-up

protection and power savings

• Fast Settling APC Amplifier

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).

Output current pulses are enabled when an ‘L’ signal is applied to the

OUTEN pin. No output current flows when OUTEN is ‘H’, and addi-

tional laser diode protection is provided since the OUTEN input will

float high when open. Complete I_OUTshut-off is also achieved by

holding the ENABLE pin low, which will override all other control

pins.

Applications

• CD-RW applications

• Writable optical drives

• Laser diode current switching

The EL6288C 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.
