TFP401A和TFP401的区别就在于TFP401A内部集成了去抖电路,可以用示波器量下HSYNC的波形。
The TFP401A incorporates additional circuitry to create a stable HSYNC from DVI transmitters that introduce undesirable jitter on the transmitted HSYNC signal。
对 我用的一台计算机信号源没有发现噪点 另外一台就不行 但是我们都是用的都是那台在我板子上有噪点计算机的,但是这台在我这块板子有噪点的计算机直接连在显示器上没问题 我想是不是在tfp401上有调整电阻?
