Transmission Characteristics

An input signal with its frequency swept between 0.3 to 3 kHz for the receive path, or 0
to 12 kHz for the transmit path, any generated output signal with other frequency than
the input frequency will stay 28 dB below the maximum input level of 0 dBM0.
Single Frequency Distortion

The quality of Transhybrid-Balancing is very sensitive to deviations in gain and group
delay - deviations inherent to the SICOFI-4-
μ
C A/D- and D/A-converters as well as to all
external components used on a line card (SLIC, OP’s etc.)
Measurement of SICOFI-4-
μ
C Transhybrid-Loss: A 0 dBm0 sine wave signal and a
frequency in the range between 300-3400 Hz is applied to the digital input. The resulting
analog output signal at pin
V
OUT
is directly connected to
V
IN
, e.g. with the SICOFI-4-
μ
C
testmode “Digital Loop Back via Analog Port”. The programmable filters FRR, AR, FRX,
AX and IM are disabled, the balancing filter TH is enabled with coefficients optimized for
this configuration (
V
OUT
=
V
IN
).
The resulting echo measured at the digital output is at least X dB below the level of the
digital input signal as shown in the table below. (Filter coefficients will be provided)
Transhybrid Loss
The listed values for THL correspond to a typical variation of the signal amplitude and
delay in the analog blocks.
