The NJM2570A is a video amplifier with LPF under Y and C systems, with an external resistor that adjusts the LPF characteristics and optimizes the TV monitor system using the output of the 75Ω driver. In addition, the internal DC interface of the S terminal can distinguish the screen aspect ratio of the TV. NJM2570A includes power-saving circuitry, making it suitable for portable video test equipment.
