Functional Description
Agere Systrems Inc.'s TTIA0110G is a hybrid inte-
grated circuit that combines a transimpedance ampli-
fier die (TTIA0110GA) with necessary filtering to
achieve a broad dynamic range amplifier. A typical
application is a low-noise, high-speed lightwave
receiver when combined with an APD or PIN photo-
detector. The targeted transmission system is OC-
192/STM-64.
The amplifier consists of a differential transimped-
ance stage followed by an output buffer which pro-
vides complementary 50
outputs. A wide dynamic
range of linear operation is achieved by combining a
low-noise input stage with an output buffer capable of
providing a single-ended output swing of 1 Vp-p.
Large output swings provide linear operation up to
400
A average input current.
Amplifier operation is from a single 5.0 V power
supply. The amplifier is available as a die or in a
hybrid integrated circuit, which includes the bypass-
ing and overload control circuitry.
