PIN CONFIGURATION
PIN DESCRIPTIONS
DETECT (12)
This is the analog input from the laser monitor photodiode
for the integrator circuit. There is an on-board resistance
of 2M
between the DETECT input and CAP1 pin.
CAP1 and CAP2 (11 & 10)
Capacitor inputs for an external capacitor in the feedback
loop of the Mean Power Control Integrator. There is an on-
board capacitance of 500pF.
AUTOMON (6)
Active high input used to enable the internal auto-monitor
function, which provides automatic adjustments to the
modulation output currents (MODP and MODN) based on
the internal A/D output and the values stored in the
nonvolatile lookup table. This pin has an internal 100k
pullup.
ALERT# (8)
Active low, open-drain output. This pin is driven low
whenever the bias current increases beyond a predefined
nonvolatile threshold. This can be used to predict laser
failure.
SDA, SCL (4 & 5)
Data and Clock lines, respectively, whose function and
use are based on the industry standard I
2
C interface.
Lookup table values, configuration data, and D/A and A/D
registers may all be accessed via these two pins of the
SML2108. These pins have internal 100k
pullups.
A0, A1, A2 (1, 2, & 3)
Address Pins for the interface provided to allow multiple
devices on a single bus. These pins have internal 100k
pullups.
RDY# (7)
Active low, open-drain output. This pin is driven low
whenever the internal A/D is performing a conversion, or
while the on-board EEPROM is being programmed.
EXT TEMP (9)
Temperature input (or no connection). This pin can be
programmed as an input to the ADC and can interface a
temperature sensor. The EXT TEMP pin is multiplexed
with the bias current to provide a means of configuring the
input to the ADC. When EXT TEMP is programmed as the
