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.
