The FMS6419 offers comprehensive filtering for set top box
or DVD applications. This part consists of a triple 6th order
filter with selectable 30MHz or 8MHz frequencies.
A 2-to-1 multiplexer is provided on each filter channel. The
triple filters are intended for either YUV or RGB signals. All
channels accept DC coupled ground-referenced 1V signals.
The filters provide 2Vpp signals into AC coupled terminated
loads. The low-pass filters are powered by 3.3V and the outputs by 5.0V.
Applications
• Cable Set top boxes
• Satellite Set top boxes
• DVD players
• HDTV
• Personal Video Recorders (PVR)
• Video On Demand (VOD)

General Description
The FMS6419 offers comprehensive filtering for set top box
or DVD applications. This part consists of triple 6th order
filters with selectable 30MHz or 8MHz frequencies and a
dual filter for filtering Y, C with a composite summer. 2 to 1
multiplexers are provided on the triple filters as well as
provisions for auxiliary input to the composite channel. The
triple filters are intended for either YUV or RGB signals.
All channels accept DC coupled ground-referenced 1V
signals. The filters outputs 2Vpp signals into AC coupled
terminated loads. The low-pass filters are powered by 3.3V
and output buffers are powered by 5.0V.
The FMS6419 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 filtering from 30MHz to 8MHz on the
RGB channels. Thus, the FMS6419 addresses the requirement for a single set top box to be compatible with a variety
of resolution standards. Additionally, the product provides
6
additional filters for Y, C, and Composite Video (CV) outputs. Multiplexers on the RGB and CV channels provide
further flexibility.
For DVD applications, the product provides filtering and
output drive amplification for 6 channels of outputs. These
include R, G, B, Y, C, and CV outputs.
For Set top boxes, this product provides for 2 channels of
video to be filtered, as well as 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. The filters for the R, G,
B, Y, C, and CV channels are powered from a 3.3V supply
and the outputs from 5V.

DATA SHEET
Applications
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 on the outputs. The Y channel should
nominally have the Sync Tip at ground and be a 1V signal.
The C channel should ride around the 0.5V level. This will
ensure that the filter will utilize the optimal headroom and
avoid clipping.
DC Coupled Output Applications
The 220µF 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
0µF would create a problem. By AC coupling, the average
DC level is zero. Thus, the output voltages of all channels
will be centered around zero. Alternately, DC coupling the
output of the FMS6419 is allowable, but not recommended.
There are several tradeoffs: 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.
Driving the Digital Pins with 3.3V
or 5V Logic
Either is allowed as long as the Vih and Vil are
adhered to.
