X9520
Fiber Channel / Gigabit Ethernet Laser Diode Control for Fiber Optic Modules
DESCRIPTION
The X9520 combines three Digitally Controlled Potentiome-
ters (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.
TM
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 vari-
ous reference quantities, or as a coarse trim for one of the
other two DCPs. The 2 kbit 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.
The features of the X9520 are ideally suited to simplifying
the design of fiber optic modules which comply to the Giga-
bit Interface Converter (GBIC) specification. The integration
of these functions into one package significantly reduces
board area, cost and increases reliability of laser diode
modules.
