SY88905
Micrel
DETAILED DESCRIPTION
The SY88905 is an integrated control circuit for laser
diode modules intended for high-frequency fiber-optic
applications. The device is designed to operate with the
SY88902 laser diode driver providing Automatic Power
Control (APC) which provides bias current control and
monitor diode interface. The device also interfaces with the
SY88903 high-speed limiting amplifier providing chatter-free
Loss of Signal function.
Laser Diode Supply Current
The SY88905 provides the adjustable drive current for
the laser diode, DC bias.
Monitor Diode
The MD pin on the SY88905 provides low frequency
light intensity, laser power out feedback from the monitor
diode in the laser diode package. This feedback is used to
adjust the I
BIAS
level through the Automatic Power Control
circuit to maintain a near constant power output from the
laser diode.
