Description

The MAX3263 is a complete, easy-to-program, single +5V-powered, 155Mbps laser diode driver with complementary enable inputs and automatic power control (APC). The MAX3263 accepts differential PECL inputs and provides complementary output currents. A temperature- stabilized reference voltage is provided to simplify laser current programming. This allows modulation current to be programmed up to 30mA and bias current to be programmed from up to 60mA with two external resistors.

An APC circuit is provided to maintain constant laser power in transmitters that use a monitor photodiode. Only two external resistors are required to implement the APC function.

The MAX3263's fully integrated feature set includes a TTL-compatible laser failure indicator and a programmable slow-start circuit to prevent laser damage. The slow-start is preset to 50ns and can be extended by adding an external capacitor.
