Information - Help 
ID = 48413
       
Country:
Germany
Brand: Telefunken Deutschland (TFK), (Gesellschaft für drahtlose Telegraphie Telefunken mbH
Tube type:  IC - Integrated Circuit 
Identical to TDA2140

Base SPECIAL TUBEBASE in general
Filament Solid State
Description
  • High stability of the 4,4 MHz subcarrier oscillator against temperature and supply voltage variations
  • High noise immunity by triggering ACC and APC circuits
  • High noise immunity of the identification circuit
  • Internal generation of a combined blanking and burst key pulse by means of the flyback pulse
  • When the antenna signal decreases, chroma saturation is automatically reduced before colour killer action
  • Colour killer acts at low antenna signal, or oscillator not locked, or PAL-flipflop incorrectly identified, or no burst
  • The colour killer is working with a hysteresis
  • No adjustments of ACC level and gain are needed
  • Integrated 90° phase shifter
