MAX7438/MAX7439
General Description
The MAX7438/MAX7439 three-channel standard definition video reconstruction filters include a back-porch
clamp that sets the output blanking level of the video
signal to ground. Each channel of the MAX7438/
MAX7439 combines a lowpass filter with adjustable
high-frequency boost levels and an output buffer capable of driving two standard 150Ω video loads. The
blanking level of the output video signal on each channel is clamped to ground, eliminating the need for large
AC-coupling output capacitors. Direct input coupling
circuitry eliminates the need for AC-coupling input
capacitors. This DC-in/DC-out architecture results in
extremely low line-time distortion. The MAX7438/
MAX7439 are ideal for antialiasing and DAC smoothing
in digital video devices such as STBs, DVDs, PVRs,
and hard disk recorders. The MAX7438/MAX7439 operate from ±5V dual supplies.
The three-channel MAX7438/MAX7439 are ideal for Y,
Pb, Pr, and RGB component video signals, three composite video signals, and also Y/C plus CVBS video signals. Each filter channel achieves 60dB of attenuation at
27MHz and a maximally flat passband from DC to 5MHz.
The MAX7438 offers an internal gain of +2V/V, while the
MAX7439 offers a gain of +3V/V.

Detailed Description
Filter
The autotrimming circuit digitally controls the corner frequency to maintain the frequency characteristics over
process and temperature.
Filter Response
The MAX7438/MAX7439 reconstruction filters consist of
three separate lowpass filters with Butterworth-type
response. The filter features a maximally flat passband
for NTSC and PAL bandwidths, while maintaining good
group delay characteristics. The stopband offers excellent attenuation at frequencies of 27MHz and above
(see the Typical Operating Characteristics section).
High-Frequency Boost
The high-frequency boost compensates for signal
degradation and roll-off in the signal path prior to the
MAX7438/MAX7439 to increase image sharpness.
Program the level of high-frequency boost for each
channel by selecting the corresponding external resistor values (R HFB_-1 and R HFB_-2 , as shown in the
Typical Operating Circuit section) given in Table 1. The

H-SYNC TIP
Figure 1. Standard Video Signal
external resistors form a voltage-divider between VCC
and GND. The values in the fourth column (VHFB_ (V))
are calculated using the following equation:
VHFB_ = VCC x RHFB_-2 / (RHFB_-1 + RHFB_-2)
where VCC = 5V.
Apply an external voltage to HFB_ in place of RHFB_-1
and R HFB_-2 as an alternative. See the Electrical
Characteristics section. Filter boost modes can also be
controlled from a microprocessor. See the Applications
Information section.
Filter Bypass
The MAX7438/MAX7439 offer selectable filter bypassing that allows any of the video inputs to be filtered or
unfiltered. Select the filter bypass mode for a given
channel by setting the corresponding values for
RHFB_-1 and RHFB_-2 according to Table 1.
Output Buffer
The output buffer is able to drive two standard 150Ω
video loads with a 2VP-P signal. The MAX7438 output
buffer has a preset gain of 2V/V, and the MAX7439 output buffer has a gain of 3V/V. The MAX7439 is ideal for
a DAC output whose voltage range is between 0.67V
and 1V. Set the DAC output to 0.67V to achieve a 2V/V
signal on OUT_.
Back-Porch Clamp
The MAX7438/MAX7439 feature a back-porch clamp to
set the output blanking level. This clamp shifts the DC
level of the video signal so that the back-porch level is
close to ground (see Figure 1). The devices sense the
voltage during back porch and feed back into a control
system that provides the appropriate DC-level shift in
the filter channel to clamp the output to ground. The
back-porch clamp to ground eliminates the need for
large output-coupling capacitors that can introduce
unwanted line-time distortion (tilt), cost, and board
space. This feedback network and the on-chip capacitors introduce a finite settling time (50 lines max) after
power-up or any dramatic shift in input voltage (see the
Electrical Characteristics section).
Channel 1 requires a video signal with sync information
(CVBS, Y, or G), since the other two channels are
clamped from channel 1. In the absence of a sync on
channel 1, the circuit forces all outputs actively and
continuously to ground.
Applications Information
Power-Supply Bypassing and Layout
The MAX7438/MAX7439 operate from dual ±5V supplies. Bypass VCC and VSS to GND with 0.1µF capacitors in parallel with 1µF capacitors. Place the 0.1µF
capacitors as close to the power inputs as possible.
Since EXT is a sensitive input, place REXT close to the
device to avoid signals coupling into EXT. Do not route
any input, output, or dynamic signal near this pin and
the accompanying trace.
Note: The exposed paddle is electrically connected to
VSS.
Do not connect the exposed paddle to ground. Refer to
the MAX7438 EV kit for layout examples, as well as a
proven PC board layout example.
