Semiconductor Group
upsampled 1-bit data stream is then converted to an analog equivalent which is
smoothed by a POST-Filter (POFI). As the signal
virtual ground potential, an external capacitor is required for DC-decoupling.
Loops
There are two loops implemented. The first is to generate the AC-input impedance (IM)
and the second is to perform a proper hybrid balancing (TH). A simple extra path IM2
(from the transmit to the receive path) supports the impedance matching function.
Test Features
There are four analog and five digital test loops implemented in the SICOFI-2/4 TE. For
special tests it is possible to cut off the receive and the transmit path at two different
points. In addition, external test loops including the subscriber line measurement are
possible using the level meatering feature.
