Description

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 X9530 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 X9530 temperature compensated pro-grammable 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.
