♦ 60mA Modulation Current

The MAX3766 is a complete, easy-to-program laser

driver for fiber optic LAN transmitters, optimized for

operation at 622Mbps. It includes a laser modulator,

automatic power control (APC), and a failure indicator

with latched shutdown.

♦ 80mA Bias Current

♦ 200ps Edge Speed

♦ Modulation-Current Temperature Compensation

♦ Automatic Power Control

Laser modulation current can be programmed up to

60mA at 622Mbps. A programmable modulation tem-

perature coefficient can be used to keep the transmit-

te d e xtinc tion ra tio ne a rly c ons ta nt ove r a wid e

temperature range. The modulator operates at data

rates up to 1.25Gbps at reduced modulation current.

APC circuitry uses feedback from the laser’s monitor

photodiode to adjust the laser bias current, producing

constant output power regardless of laser temperature

or age. The MAX3766 supports laser bias currents up

to 80mA.

♦ Laser-Fail Indicator with Latched Shutdown

♦ Smooth Laser Start-Up

Ord e rin g In fo rm a t io n

The MAX3766 provides extensive laser safety features,

including a failure indicator with latched shutdown and

a smooth start-up bias generator. These features help

ensure that the transmitter output does not reach haz-

ardous levels. The MAX3766 is available in a compact

20-pin QSOP and dice.
