Application Information

The TAMC532-TM is a MTCA.4 compliant Micro Rear

Transition Module for the TAMC532. Eight RJ45

connectors are used as input connectors for the 32

differential analog inputs of the TAMC532 TM.

Each of the 32 differential analog inputs is connected to its

own filter block.

The filter block consists of an input Buffer with

programmable gain, a Gaussian shaping amplifier with

programmable shaping time and an output buffer with

adjustable baseline shift. The Pole-Zero compensation is

adjustable by use of a digital potentiometer. This is ideal

for readout of charge sensitive preamplifiers.

The baseline shift is useful if the input signal is always

positive (or negative). It allows to increase the gain and to

make better use of the ADC input voltage range.

All settings are common for groups of 8 inputs.

The output of the filter block is accessible by the AMC via

Zone 3.

A Clock input is available in the TAMC532-TM front panel

as well. A coaxial connector is used to feed the singleended

signal into the TAMC532-TM. After a single-ended

to LVDS conversion, the signal is connected to Zone 3,

RTM_CLK0.

Zone 3 pin assignment and the μRTM management

implementation are MTCA.4 compliant and comply with

Zone 3 Classification Recommendation according to

Class A2.1.
