"PANORAMA" algorithm. These TV sound processing ICs include versions for processing the multi-
channel television sound (MTS) signal conforming to the standard recommended by the Broadcast
Television Systems Committee (BTSC). The DBX noise reduction, or alternatively, Micronas Noise
Reduction (MNR) is performed alignment free. Other processed standards are the Japanese FM-FM
multiplex standard (EIA -J) and the FM Stereo Radio standard. Current ICs have to perform adjustment
procedures in order to achieve good stereo separation for BTSC and EIA-J. The MSP34x1G has
optimum stereo performance without any adjustments. All MSP 34xxG versions are pin and software
downward compatible to the MSP 34xxD. MSP34x1G further simplifies controlling software. Standard

selection requires a singleI
C transmission only. The MSP34x1G has built-in automatic functions: The
IC is able to detect the actual sound standard automatically (Automatic Standard Detection).
Furthermore, pilot levels and identification signals can be evaluated internally with subsequent

switching between mono/stereo/bilingual; no I
C interaction is necessary (Automatic Sound Selection).
