FMS6407
Features

Triple Video Drivers with Selectable HD/Progressive/SD/Bypass Filters
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 outputs to drive 1Vpp or 2Vpp signals into AC or DC coupled terminated loads with a 1Vpp input. Input signals cannot exceed 1.5Vpp and outputs can
not exceed 2.5Vpp. The FMS6407 draws 525mW from a single 5.0V supply. 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 75 loads and provide either 0dB or 6dB of gain 0.26% differential gain, 0.11 differential phase Lead-free packaging
