ML6633*
High Speed Fiber Optic LED Driver
GENERAL DESCRIPTION
The ML6633 is a high speed fiber optic LED driver suited
for networking applications up to 200 Mbps. The part is
capable of driving up to 82mA of current through a fiber
optic LED from an ECL level input signal. Its efficient
output stage provides a high current that can be
programmed for accurate absolute output level which
insures precise launch power.
The LED driver’s output stage provides a fast well
matched rise and fall time through a unique differential
output stage.
The ML6633 high speed fiber optic LED driver is
implemented in BiCMOS process and is available in an
8-pin SOIC package.
