Features
* Three channel video reconstruction filter * YUV/RGB filters * 2:1 Mux inputs for multiple RGB/YUV inputs * Selectable 8MHz to 30MHz 6th order filters for RGB (YUV) applications * 8MHz 6th order Y, C filters with composite summer * Modulator output with group delay predistortion * DC coupled input, AC coupled output * All outputs can drive AC coupled 75 loads and provide 6dB of gain * Dual multiplexed inputs * 1% differential gain with 1 differential phase * 36dB/octave roll-off on all channels
Description
The FMS6417 offers comprehensive filtering for set top box or DVD applications. This part consists of a triple 6th order filter with selectable 30MHz to 8MHz frequencies and a dual filter for filtering Y,C with a composite summer and a modulator 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 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 1Vpp signals. The filters output 2Vpp signals into AC coupled terminated loads. The low-pass filters are powered by 3.3V and the modulator and outputs by 5.0V.
Applications
* Cable Set top boxes * Satellite Set top boxes * DVD players * HDTV * Personal Video Recorders (PVR) * Video On Demand (VOD)

The low-pass filters are powered by 3.3V and the modulator and outputs by 5.0V. The FMS6417 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 30MHz to 8MHz on the RGB channels. Thus, the FMS6417 addresses the requirement for a single set top box to be compatible with a variety
REV. 2a December 2003
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 filters with composite summers. All channels provide 6dB 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 notch and group delay compensation set for NTSC specifications.
