DEVICE DESCRIPTION
The X9530 combines two Programmable Current
Generators, and integrated EEPROM with Block
Lock™
Programmable Current Generators are ideal for use in
fiber optic Modulation Current require temperature
control. The combination of the X9530 functionality
and Intersil’s Chip-Scale package lowers system cost,
increases reliability, and reduces board space
requirements.
Two on-chip Programmable Current Generators may
be independently programmed to either sink or source
current.

predefined values. Both current generators have a
maximum output of ±1.6 mA, and may be controlled to
an absolute resolution of 0.39% (256 steps / 8 bit).
Both current generators may be driven using an on-
board temperature sensor, an external sensor, or
Control Registers. The internal temperature sensor
operates over a very broad temperature range (-40

drives a 6-bit A/D converter, whose output selects one
of 64 bytes from each nonvolatile look-up table (LUT).
The contents of the selected LUT row (8-bit wide)
drives the input of an 8-bit D/A converter, which
generates the output current.
All control and setup parameters of the X9530,
including the look-up tables, are programmable via the
2-wire serial port.
