9 General Description The FMS6417A offers comprehensive filtering for set top box or DVD applications. This part consists of a triple 6th order filter with selectable 3MHz or 8MHz frequencies and a dual filter for filtering Y,C with a composite summer and a modulator channel with sound-notch and FCC group delay compensation. The modulator provides sound-notching and FCC group delay compensation for NTSC. 2-to-1 multiplexers are provided on the triple filters as well as provisions for auxiliary inputs to the composite channel. The triple filters are intended for either YUV or RGB signals. All channels accept DC coupled ground-referenced 1V signals. The filters output 2V pp signals into AC coupled terminated loads. The low-pass filters are powered by 3.3V and the modulator and outputs by 5.V. The FMS6417A is a next generation filter solution from Fairchild Semiconductor, addressing the expanding filtering needs for set top boxes, and DVD players. The product provides selectable filtering from 3MHz or 8MHz on the RGB channels. Thus, the FMS6417A addresses the requirement for a single set top box to be compatible with a variety of resolution standards. Additionally, the product provides additional filters for Y, C, CV, and modulator outputs. Multiplexers on the RGB and CV channel provide further flexibility. For DVD applications, the product provides filtering and output drive amplification for 7 channels of outputs. These include R, G, B, Y, C, CV, and modulator outputs. For set top boxes, this product provides for 2 channels of video to be filtered, as well as the flexibility of selectable high order filtering for multiple resolution standards. Additional flexibility is provided by the additional Y,C filterswith composite summers. All channels provide gain, accept 1V ground referenced inputs, and drive AC coupled loads. The filters for the R, G, B, Y, C, and CV channels are powered from a 3.3V supply and the modulator channel and outputs from 5V. The modulator channel has sound-notch and FCC group delay compensation set for NTSC specifications. FMS6417A Rev. 2A 9
