Selectable RGB (YUV) HD/SD Video Filter Driver With Y, C, Composite, And Modulator Outputs

The FMS6417 offers comprehensive ltering for set top box or DVD applications. This part consists of a triple 6th order lter with selectable 30MHz to 8MHz frequencies and a dual lter for ltering Y,C with a composite summer and a modu- lator channel with notch and group delay compensation. The Modulator provides notching and group delay compensation for NTSC. 2 to 1 multiplexers are provided on the triple lters as well as provisions for auxiliary inputs to the composite channel. The triple lters are intended for either YUV or RGB signals. All channels accept DC coupled ground-referenced 1Vpp signals. The lters output 2Vpp signals into AC coupled terminated loads. The low-pass lters are powered by 3.3V and the Modulator and outputs by 5.0V. By Fairchild Semiconductor
