General Description
The MAX3905 150Mbps automotive VCSEL driver
implements low-cost transmitters operating from 8Mbps
to 150Mbps at junction temperatures up to +140°C. The
device accepts single-ended TTL, differential PECL or
LVDS input data, and provides bias and modulation
currents for driving a VCSEL. The output is DC-coupled
to the VCSEL to minimize component count.
The driver provides temperature compensation to
VCSEL high and low currents. Adjustments of the bias
current, modulation current, bias-current temperature
coefficient, and center of the temperature-stable bias
current region are all programmable by wirebond
options. The power-reduction feature decreases output
modulation by approximately 50%. The data squelch
feature disables the VCSEL current when no data is
present.
The MAX3905 is available in die form and operates
from -40°C to +140°C junction temperature, over a +3.0V
to +5.25V supply range.
