CXB1818Q
Laser Diode Driver
Description
The CXB1818Q is a high-speed monolithic Laser
Diode Driver/Current Switch with ECL/PECL input
level. Open collector outputs are provided at the
output pins (Q, QBX) and have the capacity of driving
modulation current of 50mAp-p at a maximum data
rate of 622Mbps. Along with the modulation current
generator there is the laser diode bias current
generator which has capacity of sourcing up to 60mA
(Bias). The laser diode bias current can be controlled
by either a voltage or current into the bias adjust pin
(BiasAdj) and the bias set pin (SBias), depending on
how these pins are configured. Control of the bias
current is achieved through the APC (Automatic
Power Control) circuit. In order to avoid having a
large current go through the laser diode, this IC also
provides an Activity detector function for laser
protection. The Activity detector circuit detects data
edge transitions and if no data transition occurs after
a certain period, then both the modulation and bias
currents are shutdown. The bias currents are shut it
down by in order to pull down the output voltage of
APC OP.Amp.
When the automatic shutdown is conducted, it is
possible to select whether the laser diode alarm
output is activated or not. Additionally, this IC has
the DFF for the input signal correction and the
internal Duty Cycle correction circuit that can control
the falling edge of the input pulse up to a maximum
of 1.0ns(Min.).
