Product Summary
The UPC1377C is a bipolar analog integrated circuit designed for horizontal deflection circuit and vertical deflection circuit of color TV set. The UPC1377C consists two synchronization signal separators, vertical oscillator, vertical saw tooth shaper, vertical predrive, vertical retrace blanking pulse generator, horizontal AFC, horizontal oscillator, horizontal predriver and abnormal high voltage prevention circuit in it.
Parametrics
UPC1377C absolute maximum ratings: (1)Power supply voltage for vertical part: 15V; (2)Power supply current drain for horizontal part: 30mA; (3)Vertical output current: -30 to 0mA; (4)Horizontal output current: -10 to 10mA; (5)Power dissipation: 600mW; (6)Operating temperature: -20 to 75℃; (7)Storage temperature: -40 to 125℃.
Features
UPC1377C features: (1)Provided two synchronous signal separators realizes very stable synchronization, as they are provided each of horizontal signal and vertical one independently; (2)Remarkably improved interlace tracking brought by the completely separated wiring in horizontal part and vertical one; (3)Vertical retrace blanking time can be set freely and strictly by the adjust terminal; (4)Very low drift of oscillation frequency of vertical oscillator and horizontal one against ambient temperature.
