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.
