270Mbps SFP LED Driver
General Description
The MAX3967A 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 MAX3967A’s LED prebias voltage is programmable
from 400mV to 925mV. The prebias circuit produces
