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 150Ω 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)
