Description
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.
