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.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
