Functional Description
The Lucent Technologies Microelectronics Group
TLMA0110G is a wideband limiting amplifier with dif-
ferential inputs and outputs. It provides 31dB of gain
(37dB differential) and 12GHz of bandwidth in a
50Ω environment.
The TLMA0110G is designed for use in SONET
OC-192 and SDH STM-64 receiver/regenerator
applications. Amplifier operation is from a single
–5.0V power supply. The TLMA0110G is available
as a die or in a 24-lead, hermetic, surface-mount
package.

Pin Information (continued)
Nodes FPI, FPO , FNI and FNO complete the positive and negative internal f eedback loops that are used to control
the threshold level. These pins can be connected in several different ways.
The threshold level can be adjusted by inserting a voltage source between nodes FPI and FPO or FNI and FNO.
■If the voltage source is inserted between FPI and FPO, then FNI and FNO should be shorted together.
■If the voltage source is inserted between FNI and FNO, then FPI and FPO should be shorted together.
A current source can also be used to control the threshold level. In this case, FPO is shorted to FPI and FNO is
shorted to FNI, and the current source is inserted between the positive and negative sides of the feedback loop.
If external control of the threshold lev el is not required, short FPO to FPI and FNO to FNI. This configuration will fix
the crossing point at 50%.
