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 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.
