FN8206.1
PRELIMINARY
Triple DCP, POR, 2kbit EEPROM Memory,
Dual Voltage Monitors
Features
• Three Digitally Controlled Potentiometers (DCPs)
- 64 Tap - 10kΩ
The X9520 combines three Digitally Controlled
- 100 Tap - 10kΩ
- 256 Tap - 100kΩ
- Nonvolatile
- Write Protect Function
Potentiometers (DCPs), V1/Vcc Power-on Reset (POR)
circuitry, two programmable voltage monitor inputs with
software and hardware indicators, and integrated EEPROM
with Block Lock™ protection. All functions of the X9520 are
accessed by an industry standard 2-Wire serial interface.
• 2kbit EEPROM Memory with Write Protect & Block Lock
• 2-Wire Industry Standard Serial Interface
- Complies to the Gigabit Interface Converter (GBIC)
specification
Two of the DCPs of the X9520 may be utilized to control the
bias and modulation currents of the laser diode in a Fiber Optic
module. The third DCP may be used to set other various
reference quantities, or as a coarse trim for one of the other two
DCPs. The 2kbit integrated EEPROM may be used to store
module definition data. The programmable POR circuit may be
used to ensure that V1/Vcc is stable before power is applied to
the laser diode/module. The programmable voltage monitors
may be used for monitoring various module alarm levels.
• Power-on Reset (POR) Circuitry
- Programmable Threshold Voltage
- Software Selectable Reset Timeout
- Manual Reset
• Two Supplementary Voltage Monitors
- Programmable Threshold Voltages
The features of the X9520 are ideally suited to simplifying the
design of fiber optic modules which comply to the Gigabit
Interface Converter (GBIC) specification. The integration of
these functions into one package significantly reduces board
area, cost and increases reliability of laser diode modules.

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.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
