MAX3273EGG
+3.3V, 2.5Gbps Low-Power Laser Driver
General DescriptionThe 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.
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.
The driver can provide bias current up to 100mA and
modulation current up to 60mAP-Pwith 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.
