DESCRIPTION
The X9525 combines two Digitally Controlled Potentiom-
eters (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.
The features of the X9525 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.
