The FMS6403 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 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.
