Video Amplifier, 4-Channel, with Selectable SD/HD Reconstruction Filter

The NCS2564 is a 4-channel high speed video driver with 6th order Butterworth Reconstruction filters on each channel. A first set of 3 channels has selectable Standard Definition (SD)/High Definition (HD) filters, one per channel. A fourth channel offers an extra filter driver for driving CVBS-type video signal. The NCS2564 is, in fact, a combination of a triple SD/HD video driver plus a single CVBS video driver. It is designed to be compatible with Digital to Analog Converters (DAC) embedded in most video processors. To further reduce power consumption, two enable pins are provided one for the triple driver and another one for the single driver. One pin allows selecting the filter frequency of the triple driver. 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¿ loads.
