270Mbps SFP LED Driver
MAX3967
General Description
The MAX3967 is a programmable LED driver for fiber
optic transmitters operating at data rates up to
270Mbps. The circuit contains a high-speed current dri-
ver with programmable temperature coefficient (temp-
co), adjustments for LED prebias voltage, and a disable
feature. The circuit accepts PECL data inputs, and
operates from a single +2.97V to +5.5V power supply.
The SFP LED driver can switch up to 100mA into typical
high-speed light-emitting diodes. As temperature
increases, the device’s modulation current increases
with a tempco that is programmable from 2500ppm/°C
to 12,000ppm/°C. The modulation current is pro-
grammed with a single external resistor.
The MAX3967’s LED prebias voltage is programmable
from 400mV to 925mV. The prebias circuit produces
peaking current, which improves the LED switching
speed.
Complementary current outputs help to maintain a con-
stant supply current, reducing EMI and supply noise
generated by the transmitter module. The MAX3967 is
available in die form, or in a 4mm x 4mm, 24-pin thin
QFN package.
