+3.3V, 2.5Gbps Low-Power Laser Driver

General Description

Features

The MAX3273 is a compact, low-power laser driver for

applications up to 2.7Gbps. The device uses a single

+3.3V supply and typically consumes 30mA. The bias

and modulation current levels are programmed by

external resistors. An automatic power-control (APC)

loop is incorporated to maintain a constant average

optical power over temperature and lifetime. The laser

driver is fabricated using Maxim’s in-house, second-

generation SiGe process.

ꢀ 30mA Power-Supply Current

ꢀ Single +3.3V Power Supply

ꢀ Up to 2.7Gbps (NRZ) Operation

ꢀ Automatic Average Power Control with Failure

Monitor

ꢀ Programmable Modulation Current from 5mA to

60mA

The MAX3273 accepts differential CML-compatible

clock and data input signals. Inputs are self-biased to

allow AC-coupling. An input data-retiming latch can be

enabled to reject input jitter if a clock signal is avail-

able.

ꢀ Programmable Bias Current from 1mA to 100mA

ꢀ Typical Fall Time of 59ps

ꢀ Selectable Data Retiming Latch

ꢀ Complies with ANSI, ITU, and Bellcore

The driver can provide bias current up to 100mA and

modulation current up to 60mA

with typical (20% to

80%) edge speeds of 59ps. A failure-monitor output is

provided to indicate when the APC loop is unable to

maintain average optical power. The MAX3273 is avail-

able in a 4mm ✕ 4mm, 24-pin QFN package, as well as

in die form.
