• Disable feature for power-up

protection and power savings

• Fast Settling APC Amplifier

General Description

The EL6145C 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

OUT

output, 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

(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 only when the

OSCEN and OUTEN pins are held high. Complete control of ampli-

tude 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

OUT

shut-off is also achieved by

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

pins.

The EL6145C 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.

Applications

• CD-RW applications

• Writable optical drives

• Laser diode current switching
