www.fairchildsemi.com FMS6407 Triple Video Drivers with Selectable HD/Progressive/SD/Bypass Filters Features Three video anti-aliasing or reconstruction filters 2:1 Mux inputs for YPbPr / RGB or YPbPr / YC-CV inputs Supports D1, D2, D3 and D4 video D-connector (EIAJ CP-4120) Selectable 8MHz/15MHz/30MHz 6th order filters plus bypass for SD (480i), Progressive (480p) and HD (1080i/ 720p) AC-coupled inputs include DC restore /bias circuitry All outputs can drive AC or DC coupled 75Ω loads and provide either 0dB or 6dB of gain 0.6% differential gain, 0.4° differential phase Lead-free packaging Description The FMS6407 offers comprehensive filtering for TV, set top box or DVD applications. This part consists of a triple 6th order filter with selectable 30MHz, 15MHz, or 8MHz cutoff frequencies. The filters may also be bypassed so that the bandwidth is limited only by the output amplifiers. A 2 to 1 multiplexer is provided on each filter channel. The triple filters are intended for YPbPr, RGB and YC-CV signals. The DC clamp levels are set according to the input mux selection and the CV_SEL control input. YPbPr sync tips are clamped to 250mV, 1.125V and 1.125V respectively while RGB sync tips are all clamped to 250mV. CV mode clamps Y and CV to 250mV while C is clamped to 1.l25V. Sync clamp timing can be derived from the Y or Green input channel or from the external SYNC_IN pin. All channels nominally accept AC coupled 1Vpp signals. Selectable 0dB or 6dB gain allows the out...
