PRELIMINARY

Dual 4-Channel Driver with Oscillator

Features

• Two channels for CD or DVD

The EL6836 is a high performance,

dual output, laser driver for writeable

DVD drives. The ENA pin enables the

• Voltage-controlled output current source requiring one

external set resistor per channel

chip, while the SEL1 pin selects the I

OUT

pin. Various

• Rise time = 0.8ns

waveforms can be generated where the amplitude is

determined by the currents flowing into I , I , I , and

INR IN2 IN3

• Fall time = 0.8ns

. The timing is determined by the signals at WEN2B,

IN4

WEN3B, and WEN4B. The oscillator is enabled when OSEN

is high. The amplified I current of the selected channel is

• Channel 2 to 250mA max

• Channel 3 to 150mA max

• Channel 4 to 100mA max

INR

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

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

• Oscillator frequency to 600MHz

with the I

, I , I , and I

input. The resistor allows

the user to optimize the current gain for each channel.

• Oscillator amplitude to 100mA

• Single +5V supply (±10%)

• Chip ENAs for power savings

P-P

WEN2B, WEN3B, and WEN4B are CMOS input pins with a

1.68V threshold. Output write current pulses are enabled

when a low is applied to the WEN2B, WEN3B, or WEN4B

pin. The write current will flow to the selected output. When
