DESCRIPTION
The X9523 combines two Digitally Controlled Potenti-
ometers (DCPs), V1 / Vcc Power-on Reset (POR) cir-
cuitry, qnd two programmable voltage monitor inputs
with software and hardware indicators. All functions of
the X9523 are accessed by an industry standard 2-Wire
serial interface.
The DCPs of the X9523 may be utilized to control the
bias and modulation currents of the laser diode in a Fiber
Optic module. The programmable POR circuit may be
used to ensure that V1 / Vcc is stable before power is
applied to the laser diode / module. The programmable
voltage monitors may be used for monitoring various
module alarm levels.
The features of the X9523 are ideally suited to simpli-
fying the design of fiber optic modules . The integra-
tion of these functions into one package significantly
reduces board area, cost and increases reliability of
laser diode modules.
