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 1V
PP
signals.
Selectable 0dB or 6dB gain allows the outputs to drive
1V
PP
or 2V
PP
signals into AC- or DC-coupled terminated
loads with a 1V
PP
input. Input signals cannot exceed
1.5V
PP
and outputs cannot exceed 2.5V
PP
.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device
reliability. The absolute maximum ratings are stress ratings only.
