Description of stereodecoder
21/34
To adjust the external LEVEL voltage to the internal range two values must be defined: the
LEVEL gain LG and VSBL. To adjust the voltage where the full channel separation is
reached (VST) the LEVEL gain LG has to be defined. The following equation can be used to
estimate the gain:
Field strength voltage STEREO
The gain can be programmed through 4 bits in the "Level Gain" byte. The MONO voltage
VMO (0dB channel separation) can be choosen selecting 33, 42, 50 or 58% of REF5V.

Relation between internal and external LEVEL voltage and setup of Stereoblend

Highcut Control
The highcut control setup is similar to the stereoblend control setup : the starting point
VHCH can be set with 2 bits to be 42, 50, 58 or 66% of REF5V whereas the range can be
set to be 17 or 33% of VHCH (see
Figure 15
).
