Triple Video Drivers w/Selectable HD/Progressive/ SD/Bypass Filters for RGB and YPbPr Signals

FMS6403 Series 8.5 MHz Triple Video Drivers w / HD/PS/SD Bypass Filter TSSOP-20

The FMS6403 offers comprehensive filtering for TV, set-top box, or DVD applications. This part consists of a triple, sixth-order filter with selectable 30MHz, 15MHz, or 8MHz cutoff frequency. The filters may also be bypassed so that the bandwidth is limited only by the output amplifiers. A 2:1 multiplexer is provided on each filter channel. The triple filters are intended for YPbPr and RGB signals. The DC clamp levels are set according to the RGB_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. Sync clamp timing can be derived from the Y/G inputs or from the external SYNC_IN pin. The 8MHz and 15MHz filter settings support bi-level sync, while the 30MHz filter setting and bypass mode support tri-level sync. 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 cannot exceed 2.5VPP.
