Notice
Stresses greater than those listed under “Absolute Maximum Ratings”
may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other
conditions above those indicated in the operations section for
extended periods of time may affect reliability.
Notice
The inherent design of this component causes it to be sensitive to
electrostatic discharge (ESD). To prevent ESD-induced damage
and/or degradation to equipment, take normal ESD precautions when
handling this product

source.
3. Bandwidth and Low Frequency Cutoff are measured with a small signal sinusoidal
light source with –12dBm average power
4. RMS input referred optical noise equivalent power is obtained by measuring the RMS
output noise into a 3200 MHz, 4-pole Bessel-Thompson filter then dividing by the
responsivity. A scaling factor of 14 is used to predict a BER of 10
-12
.
5. Sensitivity is measured with an optical source with an extinction ratio of 3dB.
6. Stressed receiver sensitivity is measured with 3.5dB vertical eye closure (intersymbol
interference) and with 0.3UI of jitter added. The measurement technique is defined in
IEEE 802.3ae.
7.
Rise/Fall times are corrected for optical source Rise/Fall times.

10. Group delay is a sensitive measurement to package interface, and includes the effects
of PD, TIA and package. Measurement is made with TO leads as short as possible.

biasing of the TIA will occur, resulting in erroneous RSSI current.
