Dual 4-Channel Driver with Oscillator

Features

• Two channels for CD or DVD

The EL6838 is a high performance,

dual output, laser driver for writeable

• Voltage-controlled output current source requiring one

external set resistor per channel

‘super-combo’ CD - DVD drives. The

ENA pin enables the chip, while the SEL1 pin selects the

• Channel 2 to 250mA max

• Channel 3 to 150mA max

• Channel 4 to 100mA max

at OUTEN2, OUTEN3, and OUTEN4. The oscillator is

enabled when OSCEN is high. The amplified I current of

the selected channel is enabled when the ENA pin is high.

The total output current is the sum of the read current, the

enabled write currents, and the oscillator current when

enabled.

• On chip oscillator with frequency and amplitude control by

use of external resistors to ground

• Oscillator frequency to 600MHz

Usually a voltage DAC will drive a resistor that is in series

with the I

Output write current pulses are enabled when a low is

applied to the OUTEN2, OUTEN3, or OUTEN4 pin. The

write current will flow to the selected output. When SEL1 is
