The X9530 is a highly integrated laser diode bias controller which incorporates two digitally controlled Programmable Current Generators, temperature compensation with dedicated look-up tables, and supplementary EEPROM array. All functions of the device are controlled via a 2-wire digital serial interface.

Two temperature compensated Programmable Current Generators, vary the output current with temperature according to the contents of the associated nonvolatile look-up table. The look-up table may be programmed with arbitrary data by the user, via the 2-wire serial port, and either an internal or external temperature sensor may be used to control the output current response. These temperature compensated programmable currents maybe used to control the modulation current and the bias current of a laser diode.

The integrated General Purpose EEPROM is included for product data storage and can be used for transceiver module information storage in laser diode applications.
