长虹CN—5机芯彩电的主要特点是:(1)彩色小信号处理电路采用松下AN5095K/AN5195K集成电路(它是一体化中规模集成电路,有I~2C总线控制,图像及伴音检波电路均采用锁相环PLL方式)。 (2)开关电源电路采用以汤姆逊公司生产的TEA2261双极型功率管(开关管)驱动电路为核心的电
Changhong CN-5 movement color TV main features are: (1) color small signal processing circuit with Panasonic AN5095K / AN5195K integrated circuit (which is integrated in the scale of integrated circuits, I ~ 2C bus control, image and sound detection circuit are Using phase-locked loop PLL method). (2) The switching power supply circuit uses the TEA2261 bipolar power tube (switch tube) driving circuit produced by Thomson company as the core of the power
