              .--\/--.
       Gnd -- |01  28| <- Feedback clamp time constant
      Sync <- |02  27| <- Video
     Burst <- |03  26| <> Pedestal clamp time constant
    ACK TC <> |04  25| <> Chroma normalization time constant
    TP adj -> |05  24| <- Chroma
       Vcc -- |06  23| <- Chroma adj
   V phase <- |07  22| -- Vcc
       Vcc -- |08  21| -> Chroma
    APC TC <> |09  20| <- Delay Line Amplifier bias
   Hue Adj -> |10  19| <- Delay Line Amplifier
        X2 -> |11  18| -> Blue
        X1 <- |12  17| -> Green

              '------'

• ACK TC: "Auto Color Killer Time Constant"
• V phase: indicates whether PAL colorburst V component is inverted
• APC TC: "Auto Phase Control Time Constant"
