Philips Semiconductors
Preliminary specification
TV and VTR stereo/dual sound processor
with digital identification
TDA9845
FEATURES
Supply voltage 5 to 8 V
Source selector
Stereo matrix
AF input for mono source
AF outputs for Main
LED operation mode indication (stereo and dual)
High identification reliability.
GENERAL DESCRIPTION
The TDA9845 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 2.1 s; identification concerning
the main functions).
