NCS2584: Video Amplifier, 4-Channel, with Load Detection and Signal Detection
The NCS2584 is a 4 channel high speed video driver with 6th order Butterworth Reconstruction filters on each channel. A first set of 3 channels has High Definition (HD) 34 MHz filters, one per channel. A fourth channel offers an extra driver for Cvbs type video signal with an 8 MHz filter. The NCS2584 is in fact a combination of a triple HD video driver plus a single Cvbs video driver. In addition, this four channel video driver integrates an auto shutdown function in order to detect the moment when the DAC is turned on or off. It also embeds a load detection to lower the power consumption when the TV is unplugged. To further reduce the layout and software complexity, the NCS2584 will automatically turn off without any external command. These features help significantly the systems like Blu-Ray players or Set Top Boxes to be in line with the restricting energy saving standards on standby modes. It is designed to be compatible with Digital to Analog Converters (DAC) embedded in most video processors. All channels can accept DC or AC coupled signals. In case of AC coupled inputs, the internal clamps are enabled. The outputs can drive both AC and DC coupled 150 ohms loads but also two loads of 150 ohms in parallel.
