DESCRIPTION

The X9523 combines two Digitally Controlled Potentiometers (DCPs), V1 / Vcc Power-on Reset (POR) circuitry, 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.
