TYPICAL APPLICATION
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.
