1 / 30 page  REV 3.7 8/26/04 Characteristics subject to change without notice. 1 of 30 www.xicor.com X9530 Temperature Compensated Laser Diode Controller FEATURES • Compatible with Popular Fiber Optic Module Specifications such as Xenpak, SFF, SFP, and GBIC •Package —14 Pin TSSOP —15 Lead 2.7 x 3.5mm CSP (Chip-Scale Package) • Two Programmable Current Generators —±1.6 mA max. —8-bit (256 Step) Resolution • Integrated 6 bit A/D Converter • Temperature Compensation —Internal or External Sensor —–40°C to +100°C Range —2.2°C / step resolution —EEPROM Look-up Tables • Hot Pluggable • 2176-bit EEPROM —17 Pages —16 Bytes per Page • Write Protection Circuitry —Xicor BlockLock™ —Logic Controlled Protection —2-wire Bus with 3 Slave Address Bits • 3 V to 5.5 V, Single Supply Operation LASER DIODE BIAS CONTROL APPLICATIONS • SONET and SDH Transmission Systems • 1G and 10G Ethernet, and Fibre Channel Laser Diode Driver Circuits 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 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 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.
