The FMS6366 Filter Driver offers comprehensive filtering
for set top box or DVD applications. This part consists of
triple 6th order filters with selectable cutoffs for SD or HD.
The filters are in a 4:2:2 configuration such that Y1 switches
between 8MHz (SD) and 30MHz (HD). The Pb and Pr
channels switch between 4MHz (SD) and 15MHz (HD).
The required delay compensation must be performed in the
digital domain prior to filtering by the FMS6366.

Description
The FMS6366 offers comprehensive filtering for set top box
or DVD applications. This part consists of triple 4:2:2 6th
order filters with selectable 30/15MHz or 8/4MHz frequencies for YPbPr and a dual 8MHz filter for YC with a composite summer. Two-to-one multiplexers are provided on the
triple filters as well as provisions for auxiliary input to the
composite channel. The triple filters are intended for YPbPr
signals. All channels accept DC coupled ground-referenced
1Vpp signals. The filters output 2Vpp signals into AC coupled terminated loads.
The FMS6366 is a next generation filter solution from Fairchild Semiconductor addressing the expanding filtering needs
for set top boxes, and DVD players. The product provides
selectable 4:2:2 HD/SD filtering on the YPbPr channels.
Thus, the FMS6366 addresses the requirement for a single
REV. 1B September 17, 2004
set top box to be compatible with a variety of resolution standards. Additionally, the product provides additional filters
for Y, C, and Composite Video (CV) outputs. Multiplexers
on the YPbPr and CV channels provide further flexibility.
For DVD applications, the product provides filtering and
output drive amplification for 6 channels of outputs. These
include Y1, Pb, Pr, Y2, C, and CV outputs.
For Set top boxes, this product provides two channels of filtered video with the flexibility of selectable high order filtering for multiple resolution standards. Additional flexibility is
provided by the Y (Luma) and C (Chroma) filters with a
composite summer.
All channels provide 6dB gain, accept 1V ground referenced
inputs, and drive AC coupled loads.

Functional Description
DC Levels
At any given time, the input signal’s DC levels must be
between 0.0V and 1.3V to utilize the optimal headroom
and to avoid clipping at the outputs. The Y channels accept
1Vpp signals with the sync tip at ground. The Pb, Pr and C
channels should be centered around 0.5V. This will ensure
that the filter will utilize the optimal headroom and avoid
clipping.
DC-Coupled Output Applications
The 220uF capacitor coupled with the 150Ω termination
forms a high pass filter that blocks the DC while passing the
video frequencies and avoiding tilt. Lower values such as
10uF cause unacceptable tilt in the output signal. By AC
coupling, the average DC level is zero. Thus, the output voltages of all channels will be centered around zero.
Applications
DC coupling the output of the FMS6366 is allowable, but
not recommended. There are several trade-offs: The average
DC level on the outputs will be 2V. Each output will dissipate an additional 40mW nominally. The application will
need to accommodate a 1V DC offset sync tip. Also, it is
recommended to limit one 150Ω load per output.
The FMS6366 is specified to operate with output currents
typically less than 50mA, more than sufficient for a dual
(75Ω) video load. Internal amplifiers are current limited to
a maximum of 100mA and should withstand brief duration
short circuit conditions, however this capability is not guaranteed.
Driving Digital Pins
The FMS6366 digital inputs are compatible with most
3.3V and 5V logic. Verify that the Vih and Vil are within the
specified limits.
Digital Delay Compensation
A typical application for the FMS6366 is shown in Figure 1.

RT2 = 75Ω
The Chroma filters are one half the bandwidth of the
Luminance filter therefore the propagation delay time
through the Chroma filter is longer than the Luminance filter.
In the Standard Definition (SD) case, the Chroma filter
propagation delay is typically 60 nanoseconds longer than
the Luminance filter. This is three clock cycles at 54MHz so
it is easily corrected by adding digital delay as shown in
Figure 3 and illustrated as a shift register in Figure 2. In
the High Definition (HD) setting the Chroma filter propagation delay is typically 15 nanoseconds longer than the
Luminance filter. This is one clock cycle at 74.25MHz
so it is also easily corrected by adding digital delay to the
luminance path.
