TDA9874A
Information as of 2000-08-20
TDA9874A; Digital TV sound demodulator/decoder
The TDA9874A is a single-chip Digital TV Sound Demodulator/Decoder (DTVSD) for analog and digital multi-channel sound systems in
TV/VCR sets and satellite receivers.
Supported standards
The multi-standard/multi-stereo capability of the TDA9874A is of interest in Europe, Hong Kong/PR China and South East Asia. This
includes B/G, D/K, I, M and L standards. In other application areas there exist subsets of the standard combinations or only single
standards are transmitted.
All A2 (analog 2-carrier) and NICAM systems are supported. M standard (with mono or BTSC stereo sound) can be received and
processed in mono sound mode.
The AM sound of L/L’ standard is normally demodulated in the 1st sound IF. The resulting AF signal has to be entered into the mono audio
input of the TDA9874A. A second possibility is to use the internal AM demodulator stage (with 6.5 MHz intercarrier), which gives limited
performance.
Korea has a stereo sound system similar to Europe which is supported by the TDA9874A. Differences include deviation, modulation
contents and identification. It is based on M standard.
For all FM standards a high deviation mode for a single carrier monaural sound demodulation is selectable.
An overview of the supported standards, sound systems and their key parameters is given in Tables 1 to 3.
The analog multi-channel systems are sometimes also referred to as 2-carrier systems (2CS).
