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.
