DESCRIPTION

The X9521 combines two Digitally Controlled Potentiom-

eters (DCP鈥檚), and integrated EEPROM with Block

Lock

protection. All functions of the X9521 are

accessed by an industry standard 2-Wire serial interface.

The DCP鈥檚 of the X9521 may be utilized to control the

bias and modulation currents of the laser diode in a Fiber

Optic module. The 2kbit integrated EEPROM may be

used to store module definition data.

The features of the X9521 are ideally suited to simplifying

the design of fiber optic modules which comply to the Gi-

gabit Interface Converter (GBIC) specification. The inte-

gration of these functions into one package significantly

reduces board area, cost and increases reliability of laser

diode modules.
