Data Sheet

FN7220

Laser Driver Oscillator

The EL6205 consists of a variable

amplitude, push only, oscillator that

also supplies the laser DC current. It is

designed to easily interface to existing ROM controllers,

reducing parts count, and power dissipation.

The reduction of parts count and the small package allows

the oscillator to be placed closer to the laser, thus reducing

EMI. Also, the turn-on and turn-off edges are slew rate

limited to reduce higher harmonics.

The total current drawn from the power supply can be less

than the laser threshold current due to the unique push-only

modulation method. The average current is less than the

peak oscillator current, and can be less than half of the

oscillator current. The power control current supplied from

the main board is reduced to less than 2mA.

One external resistor sets the oscillator frequency. A current

applied to the IIN terminal determines the amplitude of the

oscillator and laser DC current. If the oscillator amplitude is

set very low, the output and oscillator are disabled. The part

is available in the space-saving 6-pin SOT-23 package. It is

specified for operation from 0°C to +70°C.

Features

• Low power dissipation

• Reduced parts count from the conventional solution

• User-selectable frequency from 60MHz to 600MHz

controlled with a single resistor

• User-selectable amplitude from 15mA
