Dual DCP, EEPROM Memory

The X9525 combines two Digitally Controlled Potentiometers (DCPs), and integrated EEPROM with Block Lock protection. All functions of the X9525 are accessed by an industry standard 2-Wire serial Interface The DCPs of the X9525 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 X9525 are ideally suited to simplifying the design of Fiber Optic modules which comply to the Gigabit Interface Converter (GBIC) specification. The integration of these functions into one package significantly reduces board area, cost and increases reliability of Laser Diode modules.
