μPC1031H集成电路,包含从同步、振荡到输出的全部线路,性能可靠稳定,外围电路很简单,可适用于12～17英寸的黑白电视机及6～9英寸的彩色电视机中的帧扫描电路.(一)概述及特点μPC1031H的内部结构方框图见图1.⑤、⑥脚上接入电阻、电容产生自激振荡,场同步信号亦从⑤脚注入.由振荡级产生的脉冲信号经过放大到④脚,在④脚上外接阻容充放电回路,产生所需要的锯齿波.这锯齿波送到⑦脚再放大,由①脚输出,①脚上外接偏转线圈,得到帧扫描所要求的偏转电流.
The μPC1031H integrated circuit includes all lines from synchronous, oscillating to output with reliable and stable performance. The peripheral circuit is very simple and suitable for frame scanning circuits in 12 to 17 inch black and white TVs and 6 to 9 inch color TVs. (A) Overview and Features μPC1031H the internal structure of the block diagram shown in Figure 1. ⑤, ⑥ foot access resistance, capacitance self-oscillation, field synchronization signal is also injected into the foot by the oscillation level pulse signal amplified to ④ Feet, external resistance in the foot ④ charge and discharge circuit, resulting in the sawtooth wave. This sawtooth wave to ⑦ feet and then amplified by the ① pin output, ① external deflection yoke feet, get the frame scanning required deflection current .
