Description
The R195A receiver integrates a 10 Gb/s APD and TIA
into a true surface-mount package. It is part of the
industry's first multisource agreement (MSA) to stan-
dardize surface-mount 10 Gb/s receivers. These com-
pact receivers can be mounted directly to a printed-
circuit board, thus avoiding the space, routing, and EMI
problems of a mechanical cut-out.
The R195A provides features optimized for WDM
applications, most notably, linearity and flat group
delay.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.

.
Based on human-body model of R = 1500
and C = 100 pF. In general, ESD precautions should be taken to avoid damage to the device.
Recommended Operating Conditions
Electrostatic Discharge
CAUTION: This device is susceptible to damage as a result of electrostatic discharge. Take proper precau-
tions during both handling and testing. Follow guidelines such as JEDEC Publication No. 108-A
(Dec. 1988).
TriQuint employs a human-body model (HBM) for ESD-susceptibility testing and protection-design evaluation. ESD
voltage thresholds are dependent on the critical parameters used to define the model. A standard HBM (resistance
= 1.5 k
, capacitance = 100 pF) is widely used and can be used for comparison purposes.

will be provided with each device.
4. The resistance of the thermistor is inversely proportional to the temperature. The temperature, in degree-Kelvin (T
K
), can be calculated from
the resistance value using the Steinhart-Hart equation: 1/T
K
= A + B ln(R
