RA192 OC-192/STM-64 APD Lightwave Receiver
February 2003
Description
Receiver Operation
The RA192 10 Gb/s fiber-optic receiver consists of a
high-speed APD photodetector and a wide-band linear
preamp in a pigtailed, butterfly metal package. The
fiber pigtail is internally beveled for low return loss and
is available with SC, FC, LC, or MU optical connectors.
It is designed for use in single-mode, high-speed tele-
communication applications at the SONET OC-192
and the ITU-T SDH STM-64 data rate of 9.95328 Gb/s.
At 9.95328 Gb/s, the typical room temperature sensitiv-
ity at a BER of 1 x 10
10
is 26 dBm, and the typical
room temperature overload at a BER of 1 x 10
10
is
2 dBm. The operating case temperature range for the
receiver is 0 C to 70 C.
The dc levels of the differential outputs can be adjusted
relative to each other for optimum sensitivity in noisy,
amplified systems. These outputs are centered around
a dc level of typically 0.45 V when the two outputs are
dc-coupled to 50
loads. The two outputs can also be
ac coupled. If slice level control is not needed, the FB
IN
pin (pin 14) should be left open. The TIA requires only
a 5.2 V power supply for operation. The APD photo-
diode requires a nominal bias voltage of 25 V to 36 V at
less than 1 mA.

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 operations section of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
* Device is normally reverse biased. Forward biasing the photodiode can compromise device performance and reliability.

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 EIA
Standard EIA 625.
TriQuint Semiconductor 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.
