Fiber Channel/Gigabit Ethernet Laser Diode Control for Fiber Optic Modules
Data Sheet
August 20, 2007
FN8206.2
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
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.
- Write Protect Function
™
• 2kbit EEPROM Memory with Write Protect & Block Lock
• 2-Wire Industry Standard Serial Interface
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.
- Complies to the Gigabit Interface Converter (GBIC)
specification
• 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.
• Single Supply Operation
- 2.7V to 5.5V
• Hot Pluggable
• 20 Ld Package
- TSSOP
• Pb-free available (RoHS compliant)
