Single +5V, Fully Integrated,
155Mbps Laser Diode Driver
________________General Description
The MAX3263 is a complete, easy-to-program, single
+5V-powered, 155Mbps laser diode driver with com-
plementary enable inputs and automatic power control
(APC). The MAX3263 accepts differential PECL inputs
and provides complementary output currents. A tem-
perature-stabilized reference voltage is provided to
simplify laser current programming. This allows modu-
lation 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 program-
mable slow-start circuit to prevent laser damage. The
slow-start is preset to 50ns and can be extended by
adding an external capacitor.
