MAX7449
The MAX7449, 3-channel, buffered video reconstruc-
tion filter is ideal for anti-aliasing and digital-to-analog
converter (DAC)-smoothing video applications or wher-
ever analog video is reconstructed from a digital data
stream (such as cable/satellite/terrestrial set-top boxes,
DVD players, hard-disk recorders (HDRs), and person-
al video recorders (PVRs)). This device operates from a
single +5V supply and has a flat passband out to 5MHz
with a stopband attenuation of 43dB at 27MHz. This
makes it ideal for use with NTSC, PAL, and standard-
definition digital TV (SDTV) video systems. Each output
is capable of driving two standard 150Ω video loads.
The MAX7449 processes component RGB video signals.
The output video buffers have a fixed gain of +6dB. The
output video drivers can be disabled with an external pin.
The MAX7449 is available in a 14-pin TSSOP package
with an exposed pad, and is specified over the -40°C to
+85°C extended temperature range.
