DEVICE DESCRIPTION
The X9530 combines two Programmable Current
Generators, and integrated EEPROM with Block
Lock protection, in one package. The Programmable
Current Generators are ideal for use in fiber optic
Modulation Current require temperature control. The
combination of the X9530 functionality and Xicor’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.
The
maximum
determined by using an externally connected
programming resistor, or by selecting one of three
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).

is
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
°
C
to +100
°
C). The sensor output (internal or external)
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.
The general purpose memory portion of the device is a
CMOS serial EEPROM array with Xicor’s Block Lock
TM
protection. This memory may be used to store fiber
optic module manufacturing data, serial numbers, or
various other system parameters.
