FMS6419
Selectable RGB (YUV) HD/SD Video Filter Driver with Y, C, Composite Outputs
Features
Three channel video reconstruction filters YUV/RGB filters 2:1 Mux inputs for multiple RGB/YUV inputs Selectable 8MHz or 30MHz 6th order filters for RGB (YUV) applications 8MHz 6th order Y, C filters with composite summer DC coupled input, AC coupled output All outputs can drive AC coupled 150 loads and provide 6dB of gain Dual multiplexed inputs 0.6% differential gain with 0.2 differential phase 36dB/octave roll-off on all channels

Description
The FMS6419 offers comprehensive filtering for set top box or DVD applications. This part consists of a triple 6th order filter with selectable 30MHz or 8MHz frequencies. A 2-to-1 multiplexer is provided on each filter channel. The triple filters are intended for either YUV or RGB signals. All channels accept DC coupled ground-referenced 1V signals. The filters provide 2Vpp signals into AC coupled terminated loads. The low-pass filters are powered by 3.3V and the outputs by 5.0V.

Applications
Cable Set top boxes Satellite Set top boxes DVD players HDTV Personal Video Recorders (PVR) Video On Demand (VOD)
