IIN Connection
(Refer to the equivalent circuit diagram.) Bonding
the detector cathode to IIN (and thus drawing current
from the ATA00501) improves the dynamic range.
Although the detector may be used in the reverse
direction for input currents not exceeding 25 mA, the
specifications for optical overload will not be met.

VOUT Connection
The output pad should be connected via a coupling
capacitor to the next stage of the receiver channel
(filter or decision circuits), as the output buffers are
not designed to drive a DC coupled 50 ohm load
(this would require an output bias current of
approximately 36 mA to maintain a quiescent 1.8
Volts across the output load). If VOUT is connected
to a high input impedance decision circuit (>500
ohms), then a coupling capacitor may not be
required, although caution should be exercised since
DC offsets of the photo detector/TIA combination may
cause clipping of subsequent gain or decision
circuits.
