DESCRIPTION
The SA5223 is a wide-band, low-noise transimpedance amplifier
with differential outputs, incorporating AGC and optimized for signal
recovery in wide-dynamic-range fiber optic receivers, such as
SONET. The part is also suited for many other RF and fiber optic
applications as a general purpose gain block.
The SA5223 is the first AGC amplifier to incorporate internal AGC
loop hold capacitor, therefore, no external components are required.
The internal AGC loop enables the SA5223 to effortlessly handle
bursty data over a range of nA to mA of signal current, positive
direction (sinking) only.
