Overview
March 1997 ML4632 Fiber Optic LED Driver GENERAL DESCRIPTION The ML4632 is a fiber optic LED driver suited for network applications up to 20Mbps.
The part is capable of driving up to 100mA of current through a Fiber Optic LED from an ECL or TTL level input signal.
Its efficient output stage provides a high current that can be programmed for accurate absolute output level as well as automatic temperature compensation.
The combination of automatic temperature compensation and a highly accurate current driven design insures precise launch power.
The LED driver’s output stage provides fast, well matched rise and fall times through a unique class B output stage that burns supply current only when the LED is on.
A positive temperature coefficient of up to 3300ppm/°C can be programmed into the output current to compensate for the negative temperature coefficient of the LED optical output power.
An optional peaking circuit may also be employed.
The ECL and TTL inputs are ANDed so one can be u...
