The GR-gain adjustment stage is digitally programmable from – 6 to 0 dB in steps
CRAM to set GR to the desired value. After reset, the GR-gain stage is bypassed.
A low-pass filter limits the signal bandwidth in the receive direction according to ITU-T
and ETSI (NET33) recommendations.
A series of low-pass interpolation filters increases the sampling frequency up to the
desired value. The last interpolator feeds the D/A-converter.
