SY100EL1001

LASER DIODE DRIVER

WITH INPUT D FLIP-FLOP

FEATURES

DESCRIPTION

■ Up to 1.25Gb/s operation

The SY100EL1001 is a high speed current source for

driving a semiconductor laser diode in optical transmission

applications. The output current modulation is DC –

voltage controlled. The integrated circuit contains the

following functional blocks:

■ 75mA peak drive current

■ Separate modulation control

■ Separate master reset for laser safety

■ Differential inputs for data and clock

■ 75KΩ input pulldown resistor

■ Single power supply

• Input Line Receiver

• D Flip-Flop

• Bias Control Circuitry

• Output Current Switch

■ Available in 16-pin SOIC package

A logic HIGH level at the data input results in the

modulation current flowing through the OUT pin on the

next rising edge of the clock. A logic HIGH level at the

master reset input will disable the modulation current.

The device incorporates complementary open collector

outputs with a capability of driving peak current of 75

mA.

The laser driver current is adjustable by selection of

RSET. The resistor REXT must be placed between /OUT

and VCC to dissipate the worst case power. RSER is

recommended to fix laser diode matching issues.

The SY100EL1001 utilizes the high performance

bipolar ASSET™ technology.
