Fiber Channel/Gigabit Ethernet Laser Diode Control for Fiber Optic Modules Triple DCP, POR, 2kbit EEPROM Memory, Dual Voltage Monitors
FN8206 Rev 2.00 August 20, 2007
The X9520 combines three Digitally Controlled Potentiometers (DCPs), V1/VCC Power-on Reset (POR) circuitry, two programmable voltage monitor inputs with software and hardware indicators, and integrated EEPROM with Block Lock™ protection. All functions of the X9520 are accessed by an industry standard 2-Wire serial interface.
Two of the DCPs of the X9520 may be utilized to control the bias and modulation currents of the laser diode in a Fiber Optic module.
