DESCRIPTION
The X9520 combines three Digitally Controlled Potenti-
ometers (DCPs), V1 / Vcc Power-on Reset (POR) cir-
cuitry, 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.
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 moni-
tors may be used for monitoring various module alarm
levels.
The features of the X9520 are ideally suited to simplify-
ing the design of fiber optic modules which comply to
the Gigabit Interface Converter (GBIC) specification.
The integration of these functions into one package sig-
nificantly reduces board area, cost and increases reli-
ability of laser diode modules.
