GENERAL DESCRIPTION
The TDA9847 is a stereo/dual sound processor for TV and
VTR sets. Its identification ensures safe operation by using
internal digital PLL technique with extremely small
bandwidth, synchronous detection and digital integration
(switching time maximum 2.0 s; identification concerning
the main functions).
