The TDA 6621 is a single-chip TV-A2-Stereosystem Coder. The circuit can be
partitioned into two functional blocks:
1. Stereo Matrix
a) Mono, Dual, Stereo signal processing
2. Pilottone Generator
a) Line locked PLL for generating all necessary frequencies
b) External identification tone filter for filtering the square wave identification output
signal to sinusoidal waveform
c) AM-modulator with adjustment for modulation
d) Pilottone filter
The status control is handled via two TTL compatible control inputs.
Application
Headstations of central aerial television (CATV).
