MAXIM MAX9501EEE+

19-3779; Rev 1; 11/05
Triple-Channel HDTV Filters
The MAX9500/MAX9501 are fully integrated solutions
for filtering and buffering HDTV signals. The MAX9500
operates from a single +5V supply, while the MAX9501
operates from dual ±5V supplies. The MAX9500/
MAX9501 triple-channel video reconstruction filters are
both gain and delay matched and are ideal for use in
set-top boxes, DVD players, and other equipment that
generate analog HDTV outputs.
The MAX9500/MAX9501 interface between the currentoutput, digital-to-analog converters (DAC) of an
Advanced Television Standard Committee (ATSC),
Motion Picture Experts Group (MPEG) decoder and the
external connections of a television, set-top box, or
DVD player.
The MAX9500/MAX9501 feature a DC-coupled input with
very low input capacitance and high resistance. The
highly selective lowpass filters remove spectral replicas
at the output of the DAC. The output amplifier has +6dB
of gain to drive 75Ω back-terminated loads to unity gain.
The DC-coupled input eliminates problems such as sync
crush, droop, and field tilt. The output load can be DC- or
AC-coupled, depending on the application.
All three channels in the MAX9500/MAX9501 have the
same frequency response with matched group delay
and gain. The MAX9500/MAX9501 filter response meets
the requirements of the EIA-770.3/SMPTE274M filter
template achieving > 40dB attenuation at 44.25MHz.
The MAX9500/MAX9501 can also be used as an antialiasing filter for HDTV component inputs.
The MAX9500/MAX9501 are available in 16-pin SO and
compact 16-pin QSOP packages, and are fully specified
over the –40°C to +85°C extended temperature range.

Output Buffer
The MAX9500/MAX9501 output buffers provide +6dB of
gain and can drive 2VP-P into a single or double back-terminated load (150Ω or 75Ω, respectively) directly to
ground. The output can be AC-coupled or DC-coupled.
Applications Information
Input Considerations
The MAX9500/MAX9501 inputs are normally DC-coupled. No AC-coupling capacitors are required because
the input voltage range includes ground and extends
up to 1.4V, allowing the MAX9500/MAX9501 to be
directly connected to the output of a single-supply, current-output DAC without any external bias network.
The MAX9500/MAX9501 inputs can be AC-coupled.
Use a fixed bias or video clamp to set the DC bias to
ensure that the negative peak of the video signal is as
near to 0V as possible. A video clamp is preferred
because it limits the total swing of the signal and holds
the blanking level constant.

Detailed Description
The MAX9500/MAX9501 are fully integrated solutions
for filtering and buffering HDTV signals. The MAX9500
operates from a single +5V supply, while the MAX9501
operates from dual ±5V supplies. The MAX9500/
MAX9501 interface between the current-output DACs of
an ATSC, MPEG decoder, and the external connections
of a television, set-top box, or DVD player. The
MAX9500/MAX9501 feature a DC-coupled input buffer
with very low input capacitance, highly selective lowpass filters to remove out-of-band noise, and a gain of
+6dB in the output amplifier to drive 75Ω back-terminated loads to unity gain. The DC-coupled input buffer
eliminates sync crush, droop, and field tilt. The output
load can be DC- or AC-coupled.
Filter
The MAX9500/MAX9501 reconstruction filters feature a
6th-order elliptical response, providing a 1.5dB flat
passband response up to 30MHz. The filter meets the
selectivity requirements of the EIA-770.3/SMPTE 274M
filtering template, achieving > 40dB attenuation at
44.25MHz. The MAX9500/MAX9501 can also be used
as anti-aliasing filters for HDTV component inputs.
Output Considerations
The MAX9500/MAX9501 outputs are normally DC-coupled, so no AC-coupling capacitors are required. For 0V
input, the MAX9500 output voltage is 0.8V and the
MAX9501 output voltage is 0V, typical. Connect the
MAX9500/MAX9501 directly to a video cable with a 75Ω
series back-termination resistor to match the impedance
of the cable. Properly terminate the other end of the
cable with a 75Ω load. The MAX9500/MAX9501 outputs
can sink and source current allowing the device to be
AC-coupled. However, AC-coupling the outputs will
degrade the tilt.
Power-Supply Bypassing and Layout
Considerations
The MAX9500 operates from a single +5V supply while
the MAX9501 operates from dual ±5V supplies. Bypass
VCC and VEE (MAX9501) to GND with a 0.1µF capacitor
as close to the device as possible, and an additional
1µF capacitor in parallel if any significant low-frequency
disturbances are present in the vicinity of the
MAX9500/MAX9501. Use an extensive ground plane to
ensure optimum performance.
The input and output termination resistors should be
placed as close to the device as possible to avoid performance degradation in the frequency response.
The PC board traces at the output should have 75Ω
characteristic impedance when matching into a 75Ω
characteristic impedance cable. Keep the board trace
at the inputs and outputs of the MAX9500/MAX9501 as
short as possible to minimize the parasitic stray capacitance and noise pickup.
