DESCRIPTION

The X9525 combines two Digitally Controlled Potentiometers (DCP’s), and integrated EEPROM with Block Lock™ protection. All functions of the X9525 are accessed by an industry standard 2- Wire serial interface.

The DCP’s 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.
