PAL decoder TDA3565
GENERAL DESCRIPTION
The TDA3565 PAL decoder contains all the functions required for PAL signal decoding and colour matrixing and is
contained within an 18-pin package. The oscillator, a.c.c. detector and burst phase detector each have single-pin outputs
and the coupling capacitor for the luminance input at pin 8 doubles as a storage capacitor for the black level clamping
circuit. Black level clamping of the three colour channels is performed using feedback proportional to the red channel
black level. This feedback (variable with the brightness control) controls the input level of the luminance amplifier and
therefore the clamping levels of all three colour signal outputs.
