SGM9346
6-Channel, 6th-Order
Video Filter Driver for SD/HD
PRODUCT DESCRIPTION
FEATURES
The SGM9346 video filter is intended to replace passive
LC filters and drivers with an integrated device. Six
6th-order Butterworth filters provide improved image
quality compared to typical passive solutions. Three
channels offer fixed SD filters while the other three are
configurable between SD and HD filters.
Three Configurable 6th-Order SD/HD Filters
Three Fixed 6th-Order Standard Definition Filters
Clamp Mode Active with AC-Coupled Inputs
Clamp Mode Inactive with DC-Coupled Inputs
AC- or DC-Coupled Inputs
Single Supply Range: 3.3V to 5.5V
Available in Green TSSOP-20 Package
-40°C to +85°C Operating Temperature Range
The SGM9346 offers a fixed gain of 6dB. It may be
directly driven by a DC-coupled DAC output or an
AC-coupled signal. Internal clamp circuitry may be used if
AC-coupled inputs are required.
APPLICATIONS
The outputs can be AC- or DC-coupled. DC coupling the
output removes the need for output coupling capacitors.

SGM9346 is available in Green TSSOP-20 package. It
operates over an ambient temperature range of -40℃ to
+85℃.

This integrated circuit can be damaged by ESD if you don’t pay
attention to ESD protection. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failure to observe proper handling and installation procedures
can cause damage. ESD damage can range from subtle
performance degradation to complete device failure. Precision
integrated circuits may be more susceptible to damage because
very small parametric changes could cause the device not to
meet its published specifications.

design, specification or other related things if necessary without
notice at any time. Please contact SGMICRO sales office to get

NOTE:
Stresses beyond those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device. These
are stress ratings only, and functional operation of the device at
these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.

Video Filter Driver for SD/HD
APPLICATION INFORMATION
Functional Description
0V - 1.4V
The SGM9346 video filter provides 6dB gain from input to
output, and the input will be slightly offset to optimize the output
driver performance. The offset is held to the minimum required
value to decrease the standing DC current into the load.

Clamp

SoC
0.1μF
DAC
Output
The SGM9346 provides an internal clamp to support
AC-coupled input signals. If the input signal does not go below
ground, the input clamp will not operate. This allows DAC
outputs to directly drive the SGM9346 without an AC coupling
capacitor. The worst-case sync tip compression due to the
clamp will not exceed 7mV. The input level set by the clamp
combined with the internal DC offset will keep the output within
its acceptable range. When the input is AC-coupled, the clamp
will set the sync tip (or lowest voltage) just below ground.
Figure 2. AC-coupled Inputs, AC-coupled Outputs
NOTE: The video tilt or line time distortion will be dominated by
the AC coupling capacitor. The value may need to be increased
beyond 220μF in order to obtain satisfactory operation in some
applications.
I/O Configuration
The Figure1 and Figure 2 can be used with AC-coupled outputs
Power-Supply Bypassing and Layout
if desired.
Correct power supply bypassing is very important for optimizing
video performance in design. One 0.1µF and one 10µF
capacitors are always used to bypass VCC pin of SGM9346.
Place these two capacitors as close to the SGM9346 supply pin
as possible. A large ground plane is also needed to ensure
optimum performance. The input and output termination
resistors should be placed as close to the related pins of
SGM9346 as possible to avoid performance degradation. The
PCB traces at the output side should have 75Ω characteristic
impedance in order to match the 75Ω characteristic impedance
of the cable connecting external load. In design, keep the board
trace at the inputs and outputs of the SGM9346 as short as
possible to minimize the parasitic stray capacitance and noise
pickup.
