Dual 4-Channel Laser Diode Driver +

Oscillator

CD and DVD laser diode. Channels 2, 3, and 4 should be

used as the write channels, with switching speeds of

approximately one nanosecond rise/fall time. All four

channels are summed together at the I

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

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

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

applied to the WEN pin. No output current flows when WEN

is ‘H’ and additional laser diode protection is provided since

the WEN input will float high when open. Complete I

shutoff is also achieved by holding the ENABLE pin low,

which will override the WEN control pins.

Each laser driver has a separate ENABLE pin to allow total

shutdown of each laser driver when not in use.

An on-chip 500MHz oscillator is provided to allow output

current modulation when in read mode. The oscillator is

enabled when the OSCEN pin is held high. Complete control

of amplitude and frequency is set by two external resistors

connected to ground at pins R

in this data sheet for further explanation).
